Answer:
i think the hypotenuse 86 hope this help mark brainliest
Step-by-step explanation:
A square plus b square = c square
(a square plus 6 square =10 square,a)
a repeating decimal is placed over 9's instead of 0's. for example: 0.23 =
, but 0.232323... = 
a) x = 0.121212
b) 100(x) = 100(0.121212)
100x = 12.1212
c) 100x = 12.1212
- <u> x = 0.1212</u>
99x = 12
x = 
d) -2
<em>= -2
when simplified</em>
The number is rational becase it has a repeating decimal
The answer is 15
Since 20 times 7 is 140 and 140+75 is 215
Take 215-200 you get 15
