A tree was 4ft tall when it was planted. It grows 2ft per year. Which equation could be solved to determine how many years the tree will take to grow to a height of 16ft from the time it was planted?

the ecuation is 4+2x=16, and x is the number of years the tree needs to grow to a height of 16 ft

i dony know

step-by-step explanation:

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
