What side lengths should be used to model the rectangle?
A rectangle with an area of x2 - 4x - 12 square units is
represented by the model.
(x + 2) and (x - 6)
(x + 6) and (x - 2)
(x + 2) and (x - 10)
(x + 10) and (x - 2)

(x+2) (x-6)

this is because when you cross multiplication of the given area, how you simplify x^2 will be x and x, for 12 it will be +2 and -6 => (x+2) (x-6)

you can also use the quadratic formula, if you use the quadratic formula, turn the negative value into (x + number) and positive into (x - number)

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
