A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum: 
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs 
15^2=9^2+B^2 
225=81+B^2 
225-81=B^2 
144=B^2 (square root both sides) 
12=B

A student created a table of values to help solve the following equation: y =4x +24 and y = 2x+6...what x-value is a solution to
Yuki888 [10]

Answer:

x = negative 9 or x=-9

Step-by-step explanation:

4x+24=2x+6. We can subtract 6 from both sides to get    

4x+18=2x. After that, we can switch the sides to get    

2x-18=4x, so negative 18 (-18) is equivalent to 2x. We get

2x=-18, divide both sides by 2 to get x=(-9).
