A rectangular pool is 30 feet wide and 40 feet long. It is surrounded on all four sides by a wooden deck that is x feet wide. The total area enclosed within the perimeter of the deck is 2000 square feet. What is the width of the deck?

5 feet

Step-by-step explanation:

We are given that

Width of rectangular pool=b=30 feet

Length of rectangular pool=l=40 feet

Area of rectangle=

Using the formula

Area of rectangular pool=

Total area enclosed within the perimeter of  the deck=

Width of deck=x ft

Length of rectangular pool including wooden deck=40+2x ft

Width of  rectangular pool including wooden deck=30+2x ft

Area of rectangular pool including wooden deck=

According to question

(Dividing by 4 on both sides)

It is not possible because width cannot be negative it is always natural number.

Hence, the width of the deck=5 ft

360/29

step-by-step explanation:

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!
