Question

Which expression is an equivalent expression of 12x + 10 + 4y?

A.) 2(6x + 2y + 6)
B.) 3(4x + y + 10)
C.) 2(6x + 4y + 8)
D.) 2(6x + 5 + 2y)

Answer 1

answer is option D as on taking 2 in common 

Answer 2

You basically multiply the number outside the parentheses by everything inside.
So 2 × 6x = 12x,
2 × 5 = 10,
2 × 2y = 4y.
So your answer is 2(6x + 5 + 2y).
