Volume of a pyramid is 1/3 base x height or 1/3 b h ( rest are in the Comments
You are told x = 8y -4
Replace x in the second equation with 8y-4:
8y-4 + 8y = 6
Combine like terms:
16y-4 = 6
Add 4 to both sides:
16y = 10
Divide both sides by 16:
Y = 10/16
Simplify:
Y = 5/8
Now replace y with 5/8 do find x:
X = 8(5/8) -4 = 5-4 = 1
X = 1, y = 5/8
(1,5/8)
9 = 1 + 8x - 8
Add 8 to both sides:
17 = 1 + 8x
Minus 1 on both sides:
16 = 8x
Divide both sides by 8
2 = x

The value should be used for n, the number of periods over which the loan is repaid in 60 periods.
We have to determine
In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula?
<h3>What formula is used to calculate the monthly payment?</h3>
The value of the monthly payment is given by;

Where,
- PV is the present value or the amount of the loan.
- i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
- n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.
Therefore,
The value should be used for n, the number of periods over which the loan is repaid;
n = 6 years × 12 months/year = 60 months = 60 periods.
Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

Answer:
Step-by-step explanation:
The formula for this is:
6(6 + x) = 3(3 + 25) and
6(6 + x) = 3(28) and
36 + 6x = 84 and
6x = 48 so
x = 8
