Answer:
Step-by-step explanation:
4^2+x^2 = 15^2
x^2 = 15^2 - 4^2 = 225-16 = 209
x=sqrt(209)
x = 14.46
35divide by 3 and your answer
25 = 5^2
90 = 2 . 3 . 3 . 5
GCF is not as greedy as LCM.
GCF is just on a diet, so it takes the same number and the smallest amount.
25 and 90 both have 5.
5^2 or 5 ?
Take the smaller one.
GCF = 5
