Acarpenter is assigned the job of expanding a rectangular deck where the length is four times the width. the width of the deck is to be expanded by 3 feet and the length is to be expanded by the new width. if the area of the new rectangular deck is 124 ft larger than the area of the original deck, find the dimensions of the original deck

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
