Question

If you have a ladder that is 8 feet tall and that can extend to 15 feet tall. what is the inequality for this problem?

Answer 1

8less than or equal to x less than or equal to 15

Answer 2

I agree, and happen to have such a ladder. It gets a lot of use. When folded up it is 8 feet long and when fully extended it is 15 feet long.

Actually, when used as a stepladder, the height is a bit less than 8 feet, because of the inverted V shape. It is closer to 8 cos15 = 7.7 feet

At full extension, you still need a leaning angle of about 20 degrees, making a maximum height of 15 cos20 = 14.1 feet. The top rung should never be used

Go with the previous answer anyway.
