Answer:
The new volume is 375 cubic inches.
Step-by-step explanation:
Volume of a right square prism:
The volume of a right square prism is given by:

In which a is the length of the edge and h is the height.
A right square prism has a volume of 75 cubic inches.
This means that:

The prism is enlarged so its height is increased by a factor of 5
Edge is the same, height is 5 times. So

The new volume is 375 cubic inches.
8(1/4x + 3/4) -3 =17
First distribute which results in (8/4x + 24/4)-3 =17.
Now just simply simplify it into (2x+6)-3 =17
Then you combine like term : 2x+3 =17
Subtract 3 on both sides : 2x=14
Finally divide 2 on both sides to isolate x: x=7
