Answer:
x*(x+3)*(x^2)
Step-by-step explanation:
Width: x meters, length: x + 3 meters, height x^2 meters
It's an expression, so there's no simplifying needed.
x(x+3)(x^2)
But if I'm wrong and it's supposed to be simplified, Read the rest.
First, multiply x by x + 3
x(x + 3)
x^2 + 3x
Now, multiply x^2 + 3x by x^2
(x^2)(x^2 + 3x)
x^4 + 3x^3

Answer:
8. s(-2) = 3, s(0) = 2, s(4) = 0
Look at the table for each of the values of x in s(x) and see what the y-value is. For example, for s(-2) you look at what y is when x = -2. It would be y = 3.
9. when x = -4, so s(-4)
Look through the table to find the row where y = 4. x would be -4.
10. -1
You can see that each time x goes up by 2, y goes down by 1. This means that the next row would say x = 6 and y = -1. The predicted value of s(x) is -1.
in the figure below, what are the values of x and y? What are the measures of the four angles in the figure
Answer:
a. x=57.6, y=44.8
Step-by-step explanation:
Named the angles, check the picture for that
<ABD+<ACD=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)
<CAB+<BDC=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)
therefore:
a. 3y+x-12=180.............. equ 1
2x+y+20=180.............equ 2
From equ 1
x+3y=180+12
x+3y=192...............equ 3
From equ 2
2x+y=180-20
2x+y=160.............equ 4
Equate equ 3 and equ 4
x+3y=192...............equ 3
2x+y=160.............equ 4
Using elimation method
x+3y=192...............equ 3
2x+y=160.............equ 4
Multiple equ 3 by 1 and equ 4 by 3
x+3y=192...............equ 3 ×1
2x+y=160.............equ 4 ×3
x+3y=192
6x+3y=480
Subtract
-5x+0=-288
-5x=-288
x=57.6................... Equ 5
Replace 57.6 for x in equ 3
x+3y=192...............equ 3
57.6+3y=192
3y=192-57.6
3y=134.4
y=44.8
B. <CAB= 2x=2×57.6=115.2
<ABD= 3y=3×44.8= 134.4
<ACD=x-12=57.6-12=45.6
<BDC=y+20=44.8+20=64.8
Use the Distributive Property to expand 9(3 + x).
Answer:
Step-by-step explanation:

What’s the value of x
Answer:
-10
Step-by-step explanation:
-5x - 1 = -10x - 51
Add 10x to both sides.
5x - 1 = -51
Add 1 to both sides.
5x = -50
Divide both sides by 5.
x = -10

18x - 77=1
X - 7y=-33
Answer:
x=-33+7y
then putting value of x
18(-33+7y)-77=1

-671+126y=1
126y=670
y=670/126
Lella carns 42 dollars per week working part-time at a book store. She makes one dollar more for each book that she sells. The amount, A (In dollars), that Lella
carns In a week if she sells b books is given by the following.
A=42+ b
How much does Lella carn in a week if she sells 14 books?
Answer:
$56
Step-by-step explanation:
the equation is A=42+b
b=14 because Leila sells 14 books
substitute 14 in the equation: A=42+14
A=56
Answer:
She earns 1 dollar for each book sold
A = 42+B*1
A = 41+B
Let B = 14
A = 41+14
A = 56

Kevin from Pullman was offered a deal to write story problems for ST2 publishing Company. For every 5 he wrote he was paid $12.00. How much did Kevin get paid per problem?
Answer: $2.40
Step-by-step explanation:
If Kevin gets 12 dollars for every 5 problems, we will need to divide 12 by 5 to find the unit rate; how much Kevin gets for each problem.
12 ÷ 5 = 2.4, and in dollars it is equal to $2.40. Because of this, Kevin is paid $2.40 for each problem he makes for the ST2 publishing Company.

7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the garden is represented by 10r ^ 2 + 12r + 9 . Which expression represents the length of the third side ?
Answer: [tex]15r^2-21r+5[/tex]
Step-by-step explanation:
Given: Perimeter of triangular garden = [tex]25r^2 - 9r + 14[/tex]
The sum of two sides of the garden = [tex]10r^2 + 12r + 9[/tex]
Perimeter is the sum of all sides of a triangle.
Third side = Perimeter of triangular garden - sum of two sides of the garden
[tex]=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5[/tex]
The expression represent the third side = [tex]15r^2-21r+5[/tex].

What is the equation for an arithmetic sequence with a first term of 5 and a second term of 2? (5 points) an = 5 − 2(n − 1) an = 5 + 2(n − 1) an = 5 − 3(n − 1) an = 5 + 3(n − 1)
Answer:
an = 5 − 3(n − 1)
Step-by-step explanation:
First term,a = 5
Second term = 2
Common difference,d = 2 - 5 = -3
nth term = a + d(n - 1)
= 5 -3(n - 1)
Check
When n = 2
2nd term = 5 - 3(2 - 1)
= 5 - 3(1)
=5 - 3
= 2
2nd term = 2
Type the correct answer in the box. Use numerals instead of words. Find the area of this shape. The area of the shape is square centimeters.
Answer: 35cm²
Step-by-step explanation:
This is a composite shape so break it down into its individual shapes and get their areas then add them up to find the shape's total area.
Area of Triangle:
= 1/2 * base * height
= 1/2 * 8 * 5.75
= 23 cm²
Base = 4 + 4 = 8cm
Area of the Trapezium
= (a + b) / 2 * height
a is top length
b is bottom length
= (4 + 8) / 2 * 2
= 12 cm²
Add them up:
= 23 + 12
= 35cm²
Answer:
Answer: 35cm²

X-2y=10 x+3y=5 please hellppppppp
Answer:
x=8,y=-1
Step-by-step explanation:
x-2y=10
x=10+2y
10+2y+3y=5
5y=-5
y=-1
x-2(-1)=10
x=8
The solution to the system of equations x - 2y = 10 and x + 3y = 5 is x = 8 and y =-1
How to solve the equation?The system of equations is given as:
x - 2y = 10
x + 3y = 5
Subtract both equations
-2y - 3y = 10 - 5
Evaluate
-5y = 5
Divide both sides by -5
y = -1
Substitute y = -1 in x - 2y = 10
x - 2(-1) = 10
This gives
x + 2 = 10
Subtract 2 from both sides
x = 8
Hence, the solution to the equations is x = 8 and y =-1

What is a formula for the nth term of the given sequence?
36, -48, 64...
Answer:
A formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Step-by-step explanation:
Given the sequence
36, -48, 64...
We know that a geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Compute the ratios of all the adjacent terms
[tex]\frac{-48}{36}=-\frac{4}{3},\:\quad \frac{64}{-48}=-\frac{4}{3}[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-\frac{4}{3}[/tex]
Therefore, the given sequence is a geometric sequence.
As the first element of the sequence is
[tex]a_1=36[/tex]
so substituting [tex]a_1=36[/tex] and [tex]r=-\frac{4}{3}[/tex] in the nth term
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Therefore, a formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
