B:
Explanation that equation is the B
Answer:
w=p/2-l
Step-by-step explanation:
you have to simplify the equation p=2(l+w).
1) Isolate the variables l and q
p/2=l+w
2) Subtract the length from the width.
p/2-l=w
3) The answer is b, or w=p/2-l
3)Principal Amount = P = $7200
Interest rate = r = 4% = 0.04
Time = t = 8 years
Formula for compounding is:

Using the values, we get:

Therefore, the compounded amount will be $9853.70
4)Principal Amount = P = $7200
Compounded Amount = A = $9853.70
Interest Earned = Compounded Amount - Principal Amount
So,
Interest Earned = 9853.70 - 7200 = $2653.70
Therefore, $2653.70 will be earned as interest over a period of 8 years.
The answer is 2 units right 3 units up
