Respuesta :

B = 2x+4
H = 3x-5

A = bh
   = (2x+4)(3x-5)
   = (2x)(3x)+(2x)(-5)+(4)(3x)+(4)(-5)
   = 6x^2 - 10x + 12x - 20
   = 6x^2 + 2x - 20

So the answer is A (6x^2 + 2x - 20) (i think)
I hope this helps you



rectangles area = length × width



area = (2x+4)(3x-5)


area = 2x.3x-2x.5+4.3x-4.5


area = 6x²+2x-20


last one is your answer
