Answer:
Step-by-step explanation:
LHS a - b = -9 - (-6) = -9 +6 = -3
RHS b-a = -6 - (- 9) = -6 +9 = 3
as LHS not equal to RHS
a-b not equal to b-a
Thus proven
The original area of the rectangle is 
<u>Explanation:</u>
width = x
length = x + 2
area of the rectangle = x (x+2)
length = x + 2 + 5 = x+7
Solving this equation, we get
x =5ft
So, original width = 5ft
original length = 5+2ft = 7ft
Thus, original area of the rectangle = 5 X 7ft =
Therefore, the original area of the rectangle is
The payments are ...
A = P(r/n)/(1 -(1+r/n)^(-nt))
where P is the principal amount, $699,000*0.80 = $559,200
r is the annual interest rate, 0.05
n is the number of compoundings per year, 12
t is the number of years.
Then
A = 559,200*(0.05/12)/(1 -(1 +0.05/12)^(-12*35)) = 2822.21
The total of 420 of these payments is $1,185,328.20, which is $626,128.20 more than the loan amount.
Jamie's total finance charge is about $626,128.20.
_____
There is always some minor adustment required in the amount of the last payment. That has not been taken into account here.
D=10
Explanations: 2d-5=3d- 15
2d- 3d =-15+5
D=10
