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

Alecsey [184]

Answer:

$x^2+5x-310=0$

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

$A=L\times W$

we can plug values

$A=x\times (x+5)$

we have area =310

so, we can set A=310

$x\times (x+5)=310$

$x^2+5x=310$

$x^2+5x-310=0$

So, equation is

$x^2+5x-310=0$
