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

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
