When vlad moved to his new home a few years ago, there was a young oak tree in his backyard. he measured it once a year and found that it grew by 262626 centimeters each year. 4.54.54, point, 5 years after he moved into the house, the tree was 292292292 centimeters tall. how tall was the tree when vlad moved into the house? \qquadspace centimeters how many years passed from the time vlad moved in until the tree was 357357357 centimeters tall? \qquadspace years

> How tall was the tree when Vlad moved into the house?

We know that the tree grew by 26 cm per year, the current height is 292 cm and 4.5 years have already passed, therefore the original height was:

original height = 292 cm – (26 cm / year * 4.5 years)

original height = 175 cm

> How many years passed from the time Vlad moved in until the tree was 357 centimeters tall?

Calculate for time using the formula:

time = (current height – original height) / 26

time = (357 cm – 175 cm) / (26 cm/ year)

time = 7 years
