SOVA2 [1]3 years ago
7 0

Answer:

The expression is true.

Explanation:

 (x^2+8x+16)(x^2-8x+16)=(x+4)^2(x-4)^2=((x+4)(x-4))^2

 We know that (a +b)(a-b) = a²-b²

 So we have ,

      ((x+4)(x-4))^2=(x^2-4^2)^2=(x^2-16)^2

 Which is Right Hand Side  given.

So, the expression is true.

horace is a professional hair stylist. let ccc represent the number of child haircuts and aaa represent the number of adult hair
Novay_Z [31]

He can give at most 2 adult haircuts with the remaining time

<h3>How many adult haircuts at most can he give with the remaining time? </h3>

The inequality is given as:

0.75C + 1.25A <= 7

Also, we have

C = 5

Substitute C = 5 in 0.75C + 1.25A <= 7

0.75 * 5 + 1.25A <= 7

Evaluate the product

3.75 + 1.25A <= 7

Evaluate the like terms

1.25A <= 3.25

Divide by 1.25

A <= 2.6

Rewrite as

A < 3

Hence, he can give at most 2 adult haircuts with the remaining time
