Answer:
B. x^3 + 3x^2
Step-by-step explanation:
Volume of a rectangular prism=width * length * height
V=w*l*h
h=3 greater than the length of the base
h=x+3
Length of the base=x
Width=x
Substituting values into the formula
V=w*l*h
=(x)*(x)*(x+3)
Multiplying
=(x^2)(x+3)
=x^3 + 3x^2
Option B is the correct answer
-7c+9=c+1 (subtract c on both sides)
-8c+9=1 (subtract 9 on both sides)
-8c=-8 (divide by -8 on both sides to get c by its self)
c=1

The answers to the questions
Answer:
x=-1
Step-by-step explanation:
x+3≠0
x≠-3
x²+5x+6=x+3
x²+5x+6-x-3=0
x²+4x+3=0
x²+x+3x+3=0
x(x+1)+3(x+1)=0
(x+1)(x+3)=0
x+3≠ 0
so x+1=0
x=-1
