An exam has 40 multiple-choice questions, each with 5 choices. Only 1 of the 5 choices for each
aliya0001 [1]

Answer:

40 divided by 5 equals 8, so the answer is D.

mel-nik [20]

Answer:

-35

Step-by-step explanation:

we have the expression

(c-b^{2})+a^{3}

For a=-3,b=-2 and c=-4

Substitute the given values of a,b and c to evaluate the expression

(-4-(-2)^{2})+(-3)^{3}

(-4-(4))+(-27)

Remember that

(+1)(-1)=-1

(-1)(-1)=+1

(-8-27)
