Question 7 • (AG Q1) Keystone Algebra 1 Block: 26-27 (DDiamond)

What is –9.2(8x – 4) + 0.7(2 + 6.3x) simplified?

Answer
A
–69.19x – 32.39
B
–69.19x + 38.2
C
–72.2x + 41.21
D
75x – 338.2

Explanation

Distribute each factor: −9.2(8x − 4) = −73.6x + 36.8, and 0.7(2 + 6.3x) = 1.4 + 4.41x. Combine like terms: (−73.6 + 4.41)x + (36.8 + 1.4) = −69.19x + 38.2. The simplified expression is −69.19x + 38.2, choice B.
