A 6 foot tree casts an 8 foot shadow. How tall is a tree that casts a 60 foot shadow at the same time of day?

i think it would be 80... i hope this helps!! :)

45 feet

Step-by-step explanation:

create a proportion of height/shadow = height/shadow

6/8 = x/60

cross-multiply:

8x = 360

x = 45

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

answer: sine
