Using the Pythagorean therom.

81 + b^{2} = 196
b^{2} = 115
b =

Hope this helps!
Answer: C=4
Step-by-step explanation:
5(5c-1)-1 = 23c + 6
1. Using PEMDAS. You know to do parenthesis first which is 5(5c-1)
Using distributive property you will get 25c-1-1 = 23c + 6
2. Simply on both sides and get 25c-2=23c+6
3. Using the rule that whatever you do on one side of the equal sign, you do on the other you can subtract 23c from both sides and get 2c-2=6. Then add 2 on both sides and get 2c=8
4. Divide both sides by 2 to get rid of the 2 and you get c=4
These are the answers for your problem
1. 11/2
2. -1/2

Answer:
12
Step-by-step explanation:
72/2 is 36
72/6 is 12
36 is a factor of 12
therefore 12 is the answer
