Which expression is equivalent to 4(3+ 5) - 3 • 9^2? A.17 - (27)^2
B.12 + 20 - 54
C. 4(8) - 3 • 81
D. 14 • 81

D

Is your answer.

Glad I could help!

Step-by-step explanation:

4 × 3 = 12 + 5 = 17 - 3 = 14 × 9² = 1134

A. -712

B. -22

C. -211

D. 1134.

1) Given
2) Adding segments AB and BC together gives AC (Addition postulate, not too sure about the terminology) 
3) Segment Addition postulate 
4) Segment Addition postulate(Knowing that AC=BD, the distance between BC and CD add up to BD, shown in #3. AB and BC add together to give AC) 
5) Subtraction property of Equality 

Hope I helped :)
