Question 12

evaluate

-12.8

Step-by-step explanation:

Replace the letters with the respective values ( a = 4, b = 2, c = 3).

So (-3a+4b)^3 would become (-3 (4) + 4 (2))^3 = (-12 + 8)^3 = -4^3 = -64

And the bottom part (2c -1) would become (2 (3) - 1) = 6-1 = 5

So the final result would be -64 / 5 which is approximately -12,8
