The perimeter of parallelogram WXYZ is 22
You would be subtracting by 5 so the next three would be -16, -21, -26
4*d^(-3)*d^18 = 4*d^(18-3) = 4*d^(15). The trick here is to combine the exponents.
Another way to write this problem would be:
4*d^18
---------- . Here d^18 divided by d^3 results in d^15, so again the final
d^3 answer is 4*d^15.
The answer would be multiplication and subtraction
