Question

Ayuda porfis, antes de que me dê una crisis​

Answer 1

Respuesta:

A= (bxh) /2

2160m²= [(x+40)(x+82)]/2

4320 = x²+122x +3280

X²+ 122X +3280 - 4320= 0

X²+122x - 1040 =0

(x+ 130) (x- 8)=0

x+130 =0

X= - 130.

X-8= 0

X= 8

Comprobamos

A= (bxh) /2

2160m²= [(x+40)(x+82)]/2

2160m²= [(8+40)(8+82)/2

2160m²= [(48)(90)]/2

2160m²= 4.320/2

2160m²= 2160m²

520 (2
