Which number line model represents the expression -4+7.5 ;; A < -9 l l -6 l l -3 l l 0 l l 3 l l 6 > ;; B < -9 l l -6 l l -3 l l 0 l l 3 l l 6 > ;; C < -9 l l -6 l l -3 l l 0 l l 3 l l 6 >

how long did the flood last

step-by-step explanation:

then i will answer

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
