Answers:
A.) -x^3 + 6x^2 + 9
B.) -x^3 + 2x^2 - 9
C.) 5x^3 - 2x^2 - 2x - 9
D.) 5x^3 - 2x^2 + 2x + 9​

D

Step-by-step explanation:

We want to find the difference between the two polynomials:

Distribute the negative:

Rearrange the terms:

Combine like terms. Hence:

Our answer is D.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

if you need just tell me and i will come to the rescue.
