Question

evaluate the following expression using the values given: find 3x2 − y3 − y3 − z if x = 3, y = −2, and z = −5.

Answer 1

The Answer is 35 if you multiplying if not the answer is 48

Answer 2

48

Explanation:

3(3)^2= 3*9=27

(-2)^3=(-8)

repeat (-2)^3=(-8)

z=(-5)

So,

27-(-8)-(-8)-(-5) simplify 27+8+8+5

Your answer would be: 48
