B) 8x+5y=-28

3x+2y=-11

Resolver las siguientes ecuaciones por el sistema de ecuaciones del método SUMA Y RESTA:

A) 5x+6y=20

4x-3y=-23

the answer is c.

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
