Should be a) difference of squares since 25 and 9 are both perfect squares. A radical will simply that into (5-3) squared, which equals 16.

Emily thought of a counting number, and then she added the next counting number to it. She got the sum of 57. What was Emily’s n
Dovator [93]
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
                                       2x=56
                                       x=28

Answer:

see below

Step-by-step explanation:

take f(x)=5x-6, which is y=5x-6

switch the y for x and x for y and you get

x=5y-6

then add 6 on both sides and you get

x+6=5y

now divide both sides by 5 and you get

y=(x+6)/5

which is the inverse of the original function

Factor completely 625x8 − 1. (25x4 − 1)(25x4 1) (5x2 − 1)(5x2 1)(25x4 − 1) (5x2 − 1)(5x2 1)(5x2 1)(5x2 1) (5x2 − 1)(5x2 1)(25x4
GREYUIT [131]

The complete factor of the polynomial  625x⁸ − 1 is (25x⁴ + 1)(25x⁴ − 1). Then the correct option is A.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Factor completely 625x⁸ − 1.

We know that

\rm   a^2 - b^2 = (a+b)(a-b)

(25x⁴)² − 1²

(25x⁴ + 1)(25x⁴ − 1)

The complete factor of the polynomial  625x⁸ − 1 is (25x⁴ + 1)(25x⁴ − 1). Then the correct option is A.
