Question

The dimensions of a rectangle are 2x - 5 and 3x – 4. Which expression

best represents the area of the rectangle in simplest terms?

A. -17x^2 -20
B. 6x^2 -23x +20
C. 6x^2 +20
D. 6x^2 -7x -20

Answer 1

so you would rewrite them as (2x-5)(3x-4)

then multiply 2x×3x=6x^2 then -5×-4=20

so the expression is C. 6x^2+20
