Grade 7 Math Sample Question 20

Simplify this expression.

4(8x + 3) + 3(2x + 6)

A) 36x + 6

B) 38x + 30 (Correct Answer)

C) 44x + 36x

D) 80x

Explanation:
Using the Distributive Property:

4(8x + 3) = 4(8x) + 4(3) = 32x + 12

3(2x + 6) = 3(2x) + 3(6) = 6x + 18

Combining the terms: 32x + 12 + 6x + 18 = 38x + 30
