Which expression is equivalent to ? A. B. C. D.

( - ) x ( - ) = ( + )

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

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 : )
