x = 4

Step-by-step explanation:

x + x + 6 + 6 = x + 8 + 8

2x + 12 = x + 16

2x + 12 - 12 = x + 16 - 12

2x + 0 = x + 4

2x = x + 4

2x - x = x + 4 - x

2x - x = x - x + 4

x = 0x + 4

x = 0 + 4

x = 4

Chequando Respuesta :

x = 4

x + x + 6 + 6 = x + 8 + 8

(4) + (4) + 6 + 6 = (4) + 8 + 8

4 + 4 + 6 + 6 = 4 + 8 + 8

8 + 6 + 6 = 12 + 8

14 + 6 = 20

20 = 20

Ambos lados de la ecuacio'n son igual cuando x = 4, y esto confirma que la respuesta es corecta, que x = 4 en este problema.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
