Answer:
The numbers are 2 and 3. 2^2+3^2=4+9=13
Step-by-step explanation:
Answer:
13 is your answer.
let two no. be x and y
by question
x+y=5
x=5-y...........(1)
xy=6.............(2)
putting the value of x in equation 2) we get
(5-y)y=6
5y-y²=6
y²-5y+6=0
y²-3y-2y+6=0
y(y-3)-2(y-3)=0
(y-3)(y-2)=0
either
y=3
or
y=2
putting the value of y in equation 1
when y=3
x=5-3=2
when
y=2
x=5-2=3
now
when
x=3 y=2
the sum of the square of the numbers=x²+y²=3²+2²=9+4=13

Write an equivalent expression by simplifying the expression using combining like terms.
18x + 4y - 8x + 2
solve - 2/5x is less than or equal to 20
Answer:
x is less than or equal to 0
Step-by-step explanation:
- you need to multiply both sides of the inequality by 5/2
- then you reduce the numbers with the greatest common factor 5
- then you reduce the numbers with the greatest common factor 2
- any expression multiplied by 0 equals 0
- so you get x is less than or equal to 0

A savings account earns 4.5% simple interest per year. If $650 is deposited and no withdrawals are made during one year, how much interest will be earned after one year?
Answer:
$29.25
Step-by-step explanation:
The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.

Answer:
Step-by-step explanation:
I apologize if any of my answers are wrong.
For #1, WT is the same at WU, so the answer should be 7 inches
For #2, it looks like QT is just WT+QW. 7+16 is 23. Answer is 23 inches
For #3, PW is the same as QW so we can automatically assume the answer is 16 inches.
For #4, PU is the same at QT, so 23 inches
For #5, I'm pretty sure the distance between TR is the same as PT, so 8 inches for #5
For #6, PR*2 or 8*2 is 16, so 16 inches
For #7, 14 inches
For #8, 19 inches
1) Walter opened a bank account with $0. He deposits $200 in the bank
each month. Write an expression that represents how much money
Walter has deposited after some number of months (m). Which
student below is correct? What mistake do the other students make?
Student A
200*10
Student B
2200
Student C
200m
Student D
m = 200
Answer:
Student C is correct.
Students A and B do not account for the variable in the equation. Student A assumes that it has already been 10 months when it has not been stated in the question. Student B has come to the conclusion that it has been 11 months. Neither have an equation to show for it. Student D is incorrect because the variable "m" equals the number of months, and the number of months would not equal the amount of money Walter would be receiving in total. Student C is correct because the variable "m", or months, is being multiplied by 200, or the amount of money.
For example, if 5 months were to pass, then you would receive 1000 dollars, because 5×200 is 1000. This would hold up, as in the original problem, you receive 200 dollars per month. another example is if you replace "m" with 0, then it will show that in 0 months, you will have 0 dollars, and it is stated at the beginning of the problem that Walter's bank account starts at $0.

Answer:
Step-by-step explanation:
∠L = 52
∠N = 26
8) ∠M + ∠N = 180 {in trapezoid, LM // PN, co interior angles}
∠M + 26 = 180
∠M = 180 - 26
∠M = 154
11) ∠LPN + ∠L = 180 {in trapezoid, LM // PN, co interior angles}
∠LPN + 52 = 180
∠LPN = 180 - 52
∠LPN = 128
9)In ΔPAN,
∠PAN + ∠N + ∠NPA = 180 {Angle sum property}
90 + 26 + ∠NPA = 180
116 + ∠NPA = 180
∠NPA = 180 - 116
∠NPA = 64
∠LPA + ∠NPA = ∠LPN
∠LPA + 64 = 128
∠LPA = 128 - 64
∠LPA = 64
10) ∠MAP = 90 {PA ⊥ MN}

what is 3(x - 4)= 12x
Answer:
x = 4/5
Step-by-step explanation:
3(x-4)=12x
3x-12=12x
3x+12x-12=12x-12x
15x-12=0
15x-12+12=0+12
15x=12
15x/15=12/15
x = 4/5

What is equivalent to 7 x 7 x 7 x 7 x7 x 7? 7 (5 as exponent), 7 (6 as exponent), 6 (7 as exponent), 7 (7 as exponent).
Answer:
7 (6 as exponent)
Step-by-step explanation:
Given the repeated product of a number to be expressed in exponential terms, we take the number as the base and the number of times it is multiplied as the exponent or power.
As such, given 7 x 7 x 7 x 7 x7 x 7
the base is 7 and since the number of 7s being multiplied is 6, the result is
7 exponent 6 which may be written as 7^6
Answer:
Step-by-step explanation:
7^6
Over what interval is the function in this graph constant? A. 65*10 B, 1 sxs6 C. -4 sxs1 D. -10 5-4
Given:
The graph of a function.
To find:
The interval at which the graph of the function is a constant.
Solution:
From the given graph it is clear that the graph is a horizontal line and parallel to the x-axis over the interval [tex]1\leq x\leq 6[/tex].
Over the interval [tex]1\leq x\leq 6[/tex], the value of the function is constant, i.e., y=7.
It means the graph of the function is constant over the interval [1,6].
Therefore, the correct option is B.

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for
fencing. He knows that the area of the yard is 51 square meters and that the width is 5.2 meters longer
than the length. Which equation could be solved to determine the dimensions of the backyard, where the length
is / and the width is w?
0=w2+5.2w -51
o
0=12+5.21-51
4w + 10.4 = 51
о
41 +10.4 = 51
Answer:
The equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
Step-by-step explanation:
As given,
The backward is rectangular in shape
Also , we know that
Area of rectangle = 2 ( Length + Breadth )
Also, given,
Breadth of the backyard = 5.2 + Length of the backyard
Let
length of the backyard = l
Breadth of the backyard = w
∴ we get
w = 5.2 + l
⇒l = w - 5.2
and
Area = 2 ( l + w)
⇒51 = 2( w - 5.2 + w)
⇒51 = 2 ( 2w - 5.2)
⇒51 = 4w - 10.4
So, the equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
By solving we get
4w = 51 + 10.4
⇒4w = 61.4
⇒w = [tex]\frac{61.4}{4}[/tex] = 15.35
⇒ w = 15.35
⇒ l = w - 5.2 = 15.35 - 5.2 = 10.15
⇒l = 10.15
So the dimensions of the backyard = l × b = 10.15 m × 15.35 m
