Question

Simplify.

4(x − 5) + 2(y + 6) − 10

A) 4x + 2y − 18
B) 4x + 2y + 18
C) 4x + 2y − 9
D) 6xy − 15

Answer 1

A

Explanation:

Because it would be 4x - 20 + 2y + 12 - 10, 12 + -20 = -8 + -10 = -18. Therefore making it 4x + 2y -18

Answer 2

A) 4x + 2y − 18

Explanation:

4(x − 5) + 2(y + 6) − 10

Distribute

4x - 20 +2y +12 -10

Combine like terms

4x +2y -20 +12 -10

4x +2y -18
