Although you only put 2 of the 3 needed dimensions into the question, what you would do is multiply the 3 dimensions together and you would get your answer. To find the volume of a rectangular prism you multiply the width, the height, and the length.

Answers:
22.)D
23.)D

How?
Explaining number 22:
Well, let’s disprove each one of them.
A.) A is saying 6x=7. Even if we simplify that, it wouldn’t make any sense in what we are trying to do. That equation is equal to x=0.86(estimated to nearest tenth)

B.) B says that 6x=3. When we simplify this, we get x=0.5. That isn’t the number we want, so we know B isn’t right

C.) C is equivalent to 2x+2=6. Let’s simplify since it is multi-step.
2x+2=6
2x=6
x=3
Since we want x to be six, this wouldn’t be the answer either.

D.) D is saying 2x=12. When simplified, this becomes x=6. BINGO THERE IS OUR ANSWER




Explaining 23:
For this, I also used process of elimination.

Remember that x is equal to 2.5

A.)
x+3=5.5

2.5+3=5.5
5.5=5.5
That works.

B.)
2x=5
2(2.5)=5
5=5
That works.

C.)
2.5/2=1.25
1.25=1.25
That works

D.)
x-10=7.5
2.5-10=7.5
-7.5=7.5
THAT DOESNT WORK THERE IS OUR ANSWER

If f(x)=x^2+1 and g(x)=3x+1 find 2*f(4)
nadya68 [22]
F(x) = x^2 + 1
f(4) = 4^2 + 1 = 16 + 1 = 17
2*f(4) = 2 * 16 = 32
