The length of a rectangular deck is 5 feet longer than its width, x. the area of the deck is 310 square feet. which equation can be used to determine the width of the deck a- 0=x^2+5x-310. b- 0= 2x^2-310. c- 0=x^2-305. d- 0=x^2+5x-310

Step-by-step explanation:

Let's assume width of rectangular deck is x feet

so, W=x

the length of a rectangular deck is 5 feet longer than its width

so, L=x+5

we know that

area of rectangle = length*width

we can plug values

we have area =310

so, we can set A=310

So, equation is

practice. practice. practice.
