vazorg [7]

Answer:

L= 18 in

W= 8 in

Step-by-step explanation:

Step one:

The length of a rectangle is 10 inches longer than its width

let the width be x

so the lenght is x+10

the area of the rectangle is 144 square inches

Step two:

$Area= L*W\\\\144=x(x+10)\\\\144=x^2+10x\\\\x^2+10x-144=0$

the factors for the quadratic expression is

18 and -8

$x^2+18x-8x-144=0\\\\x(x+18)-8(x+18)=0\\\\x-8=0\\\\x=8\\\\x+18=0\\\\x=-18$

the width is 8 in

the length is 8+10= 18 in
