Answer:
C = 210cm^3
Step-by-step explanation:
We can get an estamate when we use the equation L x H x W = x/2
This shows 8 x 8 x 7, then divide by 2 = 224cm^3
The reason it is slightly less could be the facts the teachers want you to remember this one.
For right side prism the equation is (1/2)b x h x H
which means;
The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the right) times the height,h.
We use the side and base that surrounds the right side as (1/2)base and as side to find area then use the H as the height being the 7.
Is the whole thing divided by 6 or just the 5?
The answer is 892$ , i hope this helps u

Given:

To find:
The simplified rational expression by subtraction.
Solution:
Let us factor
. It can be written as
.
using algebraic identity.

LCM of 
Make the denominators same using LCM.
Multiply and divide the first term by (x + 1) to make the denominator same.

Now, denominators are same, you can subtract the fractions.
