2 m− 5 4 − 5 3 mstart fraction, 2, divided by, 5, end fraction, m, minus, start fraction, 4, divided by, 5, end fraction, minus, start fraction, 3, divided by, 5, end fraction, m

your answer would be 10x - 1

both equations and proportions are better.

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 : )
