Sarah was locked out of her apartment and the only way out is through a window three stories high 20 feet above the ground. She needed to borrow from one of her friends. There is a tree along the side of the house so she will need to put the ladder 15 feet from her apartment. How long does the ladder need to be to reach the apartment window?
Answer: f & b
Step-by-step explanation:
for example both leave the digits unchanged and an identity is an element of a set which, if combined with another element by a specified binary operation, leaves that element unchanged.
A/B : 4/9 = 12/B
cross multiply
(4)(B) = (9)(12)
4B = 108
B = 108/4
B = 27
P = 4a...where a is the length of one side
P = 4(27)
P = 108 yds <=== perimeter of square B
