Anything to the zeroth power is equal to 1. (The numerator is equal to one because of this rule)
So.

To solve this problem, first let x=0.933333(repeating). Then, you want to multiply both sides by 10 to get 10x = 9.33333 (repeating). Next, take equation 2 and minus equation 1 from it giving you 9x = 8.4. Finally, multiply both sides by 10 and you will get 90x = 84. Divide both sides by 90 giving x=84/90. Answer is 84/90. 84/90 can reduce to 14/15.
What were you asked to find exactly
Answer: Yes
Step-by-step explanation:
???
Similar triangles have side lengths that are proportional.
We setup a proportion using the given information.
AB/LM = BC/MN
8/12 = 14/MN
8(MN) = 12 * 14
8(MN) = 168
MN = 168/8
MN = 21
