Derek sees that a 24 foot flagpole casts a 10 foot shadow. At the same time of day, if a nearby tree casts

25 foot shadow, about how tall is the tree?

60 ft.

Step-by-step explanation:

We can solve this problem with a simple proportion:

24 / 10  =  h / 25

10h = 24 * 25

600 = 10h

60 ft. = h

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
