522 − 482 = (52 + 48)(52 − 48) = (100)(4) = 400
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.
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
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
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
b. $55 w = $605
c. $55 × w = $605
d. $55 – w = $605 – w

$625.95
$91,647
$583.45
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.
