Mrs. Shaw writes this equation on the board. She asks the students to find the solution. -40 – 2/3m + 3) = 7m - 2 a. Keith's work is shown below. What mistake did Keith make? - 40 - 6m + 1 = 7m - 2 -39 - 6m = 7m - 2 -39 = 13m - 2 -37 = 13m -2 13 = m

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 : )
