The way I would do this is to distribute the original piece and get
8 + 16x -12, which is the same as 16x -4, so C is definitely one of the answers
Next I would distribute A, which isn't an answer because 8x +14 does not equal 16x + 4. Finally I would distribute D, which comes out as 16x -4, so it is one of the answers(:
ANSWERS: C and D
I really hope this helped(:
The expression 4x^2 represents - (4)(x)(x)
2+½, is just 2½, now divided by 1/4.
let's first convert the mixed fraction to improper, and then divide.
