1.The [ ] of an Isosceles triangle is the side included between the pair of congruent angles
Answer:
Base
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles which are scalene triangle, isosceles triangle,, equilateral triangle etc..
An isosceles triangle is a triangle in which two of the sides are equal, also two angles are equal. The two equal sides of the isosceles triangle are called base while the other side is the base.
The base of an Isosceles triangle is the side included between the pair of congruent angles.
Samuel found the difference of the polynomials. (15x^2+11y^2+8x)-(7x^2+5y^2+2x)= blankx^2+6y^2+6x What value is missing from his solution?
Answer:
Co-efficient of [tex]x^{2}[/tex] is missing.
It should be 8[tex]x^{2}[/tex].
Step-by-step explanation:
Given two polynomials:
1st polynomial: [tex]15x^2+11y^2+8x[/tex]
2nd polynomial: [tex]-7x^2+5y^2+2x[/tex]
To find:
The value in the blank:
[tex](15x^2+11y^2+8x)-(7x^2+5y^2+2x)= \_\_ \ x^2+6y^2+6x[/tex]
Solution:
Here, we have 3 pair of like terms.
2 terms with [tex]x^{2}[/tex], 2 terms with [tex]y^{2}[/tex]and 2 terms with [tex]x[/tex].
Like terms can be subtracted.
Subtracting the terms with [tex]y^{2}[/tex], the coefficients will get subtracted.
[tex]11y^2 - 5y^2 = 6y^2[/tex]
Subtracting the terms with [tex]x[/tex], the coefficients will get subtracted.
[tex]8x -2x=6x[/tex]
Subtracting the terms with [tex]x^{2}[/tex], the coefficients will get subtracted.
[tex]15x^2 - 7x^2 =\bold{8}x^2[/tex]
Therefore, the answer is:
Co-efficient of [tex]x^{2}[/tex] is missing.
It should be 8[tex]x^{2}[/tex].
A triangle is inscribed in a rectangle if each vertex of the triangle lies on a side of or at a vertex of the rectangle. This diagram shows shaded triangle ACE inscribed in rectangle ABDE. Find the number of square units in the area of shaded triangle ACE, if the area of the rectangle is 13.5 square units. NEED QUICKLY
Answer:
6.75
Step-by-step explanation:
So basicly we know the area of the rectangle which really helpful.
So lets take the formula of the are for the triangle, which is b*h*1/2
So we know that the height and bass of the triangle is the same as the rectangle's legnth and width.
Meaning that we can replace b*h with 13.5.
So plug that into the quation.
13.5*1/h= Area of ACE
6.75= Area of ACE
hence, 6.75 is your answer
The area of the triangle ACE is; 6.75 square units.
According to the question; a triangle is inscribed in a rectangle with each vertex of the triangle lieing on a side of or at a vertex of the rectangle.
From the statement above, it is evident that the triangle in question covers half the area occupied by the rectangle.In essence, to find the number of square units in the area of shaded triangle ACE,
We have to divide the area of the rectangle by 2.
Therefore, the area of the triangle ACE is;
6.75 square units.

Write two expressions with unlike denominators whose sum is x-3/x+2, I need help it is confusing for me.
Answer:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Step-by-step explanation:
We need to find two expressions with unlike denominators what sum
[tex]\displaystyle S=\frac{x-3}{x+2}[/tex]
Let's suppose one of the expressions is:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
Now we subtract S minus A to find the other expression B:
[tex]\displaystyle B=S-A=\frac{x-3}{x+2}-\frac{x-2}{x+3}[/tex]
Multiply the first fraction by x+3 and the second by x+2;
[tex]\displaystyle B=(x+3)\frac{x-3}{(x+3)(x+2)}-(x+2)\frac{x-2}{(x+3)(x+2)}[/tex]
Operating:
[tex]\displaystyle B=\frac{x^2-9}{(x+3)(x+2)}-\frac{x^2-4}{(x+3)(x+2)}[/tex]
Subtracting both fractions with like denominators:
[tex]\displaystyle B=\frac{x^2-9-(x^2-4)}{(x+3)(x+2)}[/tex]
Simplifying:
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Thus the two expressions are:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
And
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]

Ryan went to the store to buy some apples. The price per pound of the apples is $4.25
per pound and he has a coupon for $2 off the final amount. With the coupon, how much would Ryan have to pay to buy 5 pounds of apples? Also, write an expression for the cost to buy p pounds of apples, assuming at least one pound is purchased.
Answer:
see below
Step-by-step explanation:
Cost for 5 pounds of apples:
($4.25 * 5 pounds) - $2 coupon
21.25 - 2
19.25
Cost of apples with p pounds: 4.25p
If one pound was purchase: 4.25p = 4.25(1) = 4.25

A store is having a Back To School Sale.The total for a skirt,a pair of shoes,and a pair of socks is $32.35 before tax.The pair of socks costs $3.75.The original prices of the skirt and shoes were the same.What was the sales price of the skirt
Answer:
The sales price of the skirt was $14.3.
Step-by-step explanation:
From the information given, you know that the total for the three items is $32.35 which is:
x+y+z=32.35
x is a skirt
y is a pair of shoes
z is a pair of socks
Also, you know that the pair of socks costs $3.75, so you can replace the value of z and subtract this from the total amount to have the price of the skirt plus the pair of shoes:
x+y+3.75=32.35
x+y=32.35-3.75
x+y=28.6
Now, as the original prices of the skirt and shoes were the same and you know that the sum of the two items is equal to $28.6, you can divide this by 2:
$28.6/2=$14.3
According to this, the answer is that the sales price of the skirt was $14.3.
A company rents a storage unit. The unit is in the shape of a cube. The formula V=s^3 can be used to find the volume of a cube. Using the formula, determine the volume of the storage unit if the side length (s) is 7 feet.
Answer:
343 cubic feet
Step-by-step explanation:
A company rents a storage unit. The unit is in the shape of a cube.
The formula V=s^3 can be used to find the volume of a cube.
Using the formula, determine the volume of the storage unit if the side length (s) is 7 feet.
From the above question
Side length (s) = 7 feet
Formula for the cube = V = s³
Volume of the cube(storage unit) = (7 feet)³
= 343 cubic feet
You are building a model of a mall. The scale factor is 6:24. The model is 9 inches tall. How tall is the actual statue?
Answer: 36 inches

It costs $11 to rent a canoe and $6.50 to use the canoe for an hour. You have $24. Write an equation that represents the number h of hours you can rent the canoe.
Answer: 11 + 6.50h = 24
You can ride on the canoe for 2 hours.
Step-by-step explanation:
24-11=13
13 divided by 6.50 is 2
So 11+6.50(2)=24
List the sides in order from the smallest to the largest
Answer:
The answer would be A, or line LJ, line KL, and line JK.
Step-by-step explanation:
You can tell which lines are smaller by using the angle measurements. The direction from which the angle is shown points to their respected line.
So, angle K goes with line LJ
Angle J goes with line LK
And angle L goes with line JK.
The size of the angle determines the size (not actual size) of the line.

Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft2. How long is the side length of the carpet?
Answer:
14.14 ft long
Step-by-step explanation:
Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft². How long is the side length of the carpet?
The Area the carpet covers is a square.
Hence, the Area of a square = (Side length)²
From the question, we are given the Area of the square = 200 ft²
Hence:
200 ft² = (Side length)²
We square root both sides.
√200 ft² = √(Side length)²
Side length = 14.142135624 ft
Approximately = 14.14 ft
The side length of the carpet is 14.14 ft long
