Check the picture below.
the volume of the prism will simply be the product of the triangular area and its length, it has a length of 8, thus

It's not entirely clear to me what you're trying to solve, but it looks like the initial equation is

First convert each term into a fraction with the same (i.e. the least common) denominator. The first term needs to be multiplied by <em>a</em> + 2; the second term by (<em>a</em> + 3) (<em>a</em> + 2); and the third term by <em>a</em> + 3 :

Now that everything has the same denominator, we can combine the fractions into one. Move every term to one side and join the numerators:

Simplify the numerator:

If neither <em>a</em> = -3 nor <em>a</em> = -2, we can ignore the denominator:

Solve for <em>a</em> :

Answer:
c.It increases.
Step-by-step explanation:
The Law of Supply and Demand states that:
The higher the prices, the higher the supply, the lower the demand. This means that at a higher price, sellers will try to sell more of the product(increasing supply), but buyers will buy less of this product(decreasing demand).
So the correct answer is:
c.It increases.
Answer:
Step 3
Step-by-step explanation:
She made her first mistake in Step 3.
This is because 4/7 is actually less than 5/3.
Step 1 and 2 are mathematically accurate.
1/2 is less than 1.
So, since 4/7 is only greater than 1/2 and not greater than 1 as compared to 5/3 which is actually greater than 1, she should have concluded that 4/7 is less than 5/3.
Therefore, Step 3 contains the mistake.
