Question

5(x + 4) + 3(x + 2) = answer box

4(x + 3) + 2(x − 4) = answer box

4(x + 2) + 2(x + 5) = answer box

A. 8x+ 4

B. 8x+ 26

C. 6x + 4

D. 7x - 18

Answer 1

5(x + 4) + 3(x + 2)
= 5x + 20 + 3x + 6
= 8x + 26

4(x + 3) + 2(x − 4)
= 4x + 12 + 2x - 8
= 6x + 4

4(x + 2) + 2(x + 5)
= 4x + 8 + 2x + 10
= 6x + 18

Therefore, the answers are:

5(x + 4) + 3(x + 2) = 8x + 26 (B)

4(x + 3) + 2(x − 4) = 6x + 4 (C)

4(x + 2) + 2(x + 5) = 6x + 18
