Question

QUICK! WHAT IS THIS ANSWER?

Answer 1

a)2x-3y

b)4(9a-4)

Explanation:

a)

we want to expand the following expression:

`\displaystyle - (1)/(4) ( - 8x + 12y)`

well to do so we consider distributive property thus distribute:

`\displaystyle - (1)/(4) (- 8x )+ - (1)/(4)( 12y)`

reduce fraction which yields:

`\displaystyle - (1)/(4) (- 8x )+ - (1)/(4)( 12y) \\ \\ \displaystyle 2x + ( - 3y)`

simplify Parentheses:

`\displaystyle \boxed{ 2x - 3y}`

b)

in the expression there's a common factor of 4 therefore factor it out:

`\displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}`
