Answer 1

Ответ:

Пошаговое объяснение:

1/2(4a-8)-1/4(8b+16)= 2a - 4 - 2b - 4 = 2a - 2b - 8

Answer 2

To simplify the expression 1/2(4a-8)-1/4(8b+16), we can follow the order of operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right). Let's break it down step by step:

1/2(4a-8) = (1/2) * (4a-8) = 2a - 4

1/4(8b+16) = (1/4) * (8b+16) = 2b + 4

Now we can substitute these values back into the original expression:

2a - 4 - (2b + 4)

Distribute the negative sign:

2a - 4 - 2b - 4

Combine like terms:

(2a - 2b) - 8

So, the simplified expression is 2a - 2b - 8.
