The width of a rectangle is 12 less than a number. Its length is 12 more than the same number. Write an expressiin for the area of the rectangle. Express you answer as a sum or difference of two terms

Sagot :

The Width is equal to X - 12 (we assume X is the number) and the Length is equal to X + 12. Using the formula, Area = Width × Length, we have: Area = (X - 12)(X + 12).
let x = be the number
(x-12)(x+12)=x2=144
x=12
