The rise and span for a roof are shown. the pitch of a roof is the ratio of the rise to the half span. if the rise is 8 feet and the span is 30 feet, what is the pitch in simplest form

  8/15

Step-by-step explanation:

Pitch = rise/half-span = (8 ft)/(1/2×30 ft) = (8 ft)/(15 ft) = 8/15

the answer will be the last one

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
