Answer:
the answer would be three because when an exponent is on the inside of the parenthesis and one is outside too, then they are multiplied. If it wasn't, then it would be added.
Step-by-step explanation:
You just add the LxW and for area you multiply LxWxLxW
It's asking you to set -x and x equal to each other...
-x = x
2x = 0
x = 0.
Initial balance : 463.76
refunds : 12.56 + 52.11 + 26.03 = 90.70
sales : 101.32 + 10.98 = 112.30
463.76 - 90.70 + 112.30 = 485.36 is the correct balance
so there is a (511.39 - 485.36) = 26.03 difference
so the mistake made was instead of subtracting the 26.03 refund, she added it as a sale
