Answer:
how many teams are there?
Step-by-step explanation:
Answer: line N
Lenght of XY: 3
Step-by-step explanation:
The line N splits <u>XY</u> into two parts
5x+8=9x+12
-9x on each side
-4x+8=12
-8 on each side
-4x=4
divide by -4 on each side
x=-1
If x is the hypotenuse then
hyp^2 = 4^2 + 5^2
hyp^2 = 41
hypotenuse =
<span>
<span>
<span>
6.403124
</span></span></span>
if x is a leg then
leg^2 = 5^2 - 4^2
leg^2 = 25 - 16
leg^2 = 9
leg =3
The 11th triangular number = 66
