Divide both sides by 1.2.
The answer is n=20.
522 − 482 = (52 + 48)(52 − 48) = (100)(4) = 400
522 − 482 = 2704 − 2304 = 400
522 − 482 = (52 − 48)2 = (4)2 = 16
Answers
52² − 48² = (52 + 48)(52 − 48) = 100 * 4 = 400
a² - b² = (a +b)*(a-b)
52² − 48² = 2704 − 2304 = 400
52² − 48² = (52 − 48)² = (4)² = 16
The optionsecond 52² − 48² = (52 + 48)(52 − 48) = (100)(4) = 400 is the correct.
What is an arithmetic operation?
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We know,
a² - b² = (a + b)(a - b)
We have:
= 52² − 48²
After using the above identity, we get:
= (52 + 48)(52 - 48)
= (100)(4)
= 400
Thus, the optionsecond 52² − 48² = (52 + 48)(52 − 48) = (100)(4) = 400 is the correct.

3x2 − 11x + 8 may or may not be a polynomial
3x2 − 11x + 8 will be a polynomial
3x2 − x + 4 may or may not be a polynomial
3x2 − x + 4 will be a polynomial
Answers
Explanation:
When we subtract polynomials, we combine like terms:
3x² is the only x² term we have.
We have -6x and subtract 5x from it; this gives us -11x.
We have 2 and subtract -6 from it; when we subtract a negative, we add the opposite, which means we have 2--6=2+6=8.
This gives us 3x²-11x+8. This is a polynomial, since it is made of monomials (none of the terms have a negative exponent or a radical sign).
Answer:
option (b) is correct.
we get a polynomial
Step-by-step explanation:
Given : Polynomial 5x -6 and .
We have to choose out of given options which shows that polynomials are closed under subtraction when polynomial 5x − 6 is subtracted from .
We first subtract the polynomial
similar terms are terms having same variables with same degree.
Here, -6x and -5x are similar
and 2 and 6 are similar.
Adding similar terms, we get,
Polynomial is an algebraic expression that can involves variables with non negative integer terms and constants.
Thus, we get a polynomial
Hence, option (b) is correct.
B. 2.56 m
C. 3.18 m
D. 0.31 m
Answers
Answer:
A. 1.59 m
Step-by-step explanation:
To find the radius of the area we wil; simply use the formula; C = 2π R
where C is the circumference of the circle, π is a constant that is always 3.14 approximately, except given otherwise and R is the radius.
From the question, since the circle is formed by roping off a rope 10 m long, then it implies that the circumference (c) = 10
We can now proceed to substitute our values into the formula;
C = 2π R
10 ≈ 2×3.14×R
10 ≈ 6.28R
Divide both-side of the equation by 6.28
(At the right-hand side of the equation 6.28 will cancel-out 6.28 leaving us with just R while at the left-hand side of the equation, 10 will be divided by 6.28)
1.592≈R
R≈1.59 m
Therefore, the radius of this area will be 1.59 m
Hope this helps.
b. $55 w = $605
c. $55 × w = $605
d. $55 – w = $605 – w
Answers
If we use w for the number of rings she sells we might ask:
$55 times how many rings she sells (w) gets her $605 in commissions.
$55 x w = $605
or you may skip the times sign (x) because when number appears next to a variable (such as w) they are connected by multiplication
so
$55w = $605 is the same thing as $55 x w = $605.
sorry for the really late answer. but its (C)

Answers
Answer:
$91,647
Step-by-step explanation:
To determine the amount that Martha is financing, you have to calculate the amount of the down payment that is a sum that she will give upfront:
$107,820 → 100%
x ← 15%
x=($107,820*15%)/100%= $16,173
Then, yoou have to subtract this amount from the price of the house:
$107,820-$16,173= $91,647
According to this, the answer is that she is financing $91,647.
Total price : 107,820
down payment 15% of the total price.
financing the remainder at 6.5% for 25 years.
How much is she financing? She will finance 85% of the total price.
107,820 * 15% = 16,173
107,820 - 16,173 = 91,647
or
107,820 * (100-15)% = 107,820 * 85% = 91,647
