Question

Which of the following choices is an equivalent expression for 12(r + t) - 6(r + t) + 4(r + t) - 2(r + t)

A

8(r - t)

B

8(r + t)

C

8r + 7t

Answer 1

B 8(r + t)

Explanation:

We must evaluate the equation in order to get the answer

12(r + t) - 6(r + t) + 4(r + t) - 2(r + t)

6(r + t) + 4(r + t) - 2(r + t)

10(r + t) - 2(r + t )

8(r + t)

The answer is B
