Question

Simplify (5 + 1)^2 - (12 + 3^2) = %3.
A. 29
B. -39
C. 5
D. -63

Answer 1

29

Explanation:

(5+1)^2-(12+3^2)/3 Add 5 and 1 = 6.

6^2-12+3^2/3 Calculate 6 to the power of 2 = 36.

36-12+3^2/3 Calculate 3 to the power of 2 = 9.

36-12+9/3 Add 12 and 9 = 21.

36-21/3 Divide 21 by 3 = 7.

36−7 Subtract 7 from 36 to get 29.
