A market's condition best determines whether a borrower’s investment on an adjustable rate loan goes up or down. The condition of the market is inversely proportional to the loan rate.
If market conditions are good then the rate goes down and if market is going down, the rate increases.
Here is your answer in the format of a PNG file.
The last would be a < 40 if you'd be going under $40.
The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2
