Since the length of this rectangle is 13 units and the width is 5 units, the area can be found this way:
A=l*w
A=13*5
A=65 so the third choice
Hope this helps!
The coefficients are 15 and 85.
the variables are x and y.
85 represents 85 dollars for each x, which is the number of shifts.
15 represents 15 dollars for each y, which is the number of dog walking jobs.
The effective rate is calculated in the following way:

where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).
our compounding period is 2 since the bank pays us semiannually(two times per year) and our interest rate is 8%
so lets plug in numbers:
Assuming the rotation is around the origin (0,0) then A' = A. The parallelogram is in its original location
