Answer:
Step-by-step explanation:
before we make out equation, we have to turn our tree heights into inches.
1 ft = 12 inches
9 ft = (9 * 12) = 108 inches
2 ft = (2 * 12) =24 inches
let x represent number of years
Type A :
108 + 17x
Type B :
24 + 24x
now it wants to know how many years till there the same height....when they will be equal.....so set them equal and solve for x
108 + 17x = 24 + 24x
108 - 24 = 24x - 17x
84 = 7x
84/7 = x
12 = x
so they will be the same height in 12 years <===
