Sheila is climbing on a ladder that is attached against the side of a jungle gym wall. She is 4 feet off the ground and is 3 feet from the base of the ladder, which is 15 feet from the wall. How high up the wall is the top of the ladder?

15 feet high

Step-by-step explanation:

Sheila - 4 feet off the ground, 3 feet horizontally form the base of the ladder.

ladder - 15 feet from the wall. 

4 : 3 = x : 15

4x15 = 4x

60 = 4x

60/4 = 4x/4

/4

15 = x

The top of the ladder is 15 feet high.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

i think it is 70
