Answer:
1. 
2.
and 
Step-by-step explanation:
We have the expression
to find the solutions we have to clear
. Then,
Add 64 in both sides of the equation.

Now we have to re-write the equation:
⇒
Then,

Apply square root on both members

Now substitute back 
1. 
2. 
Solving for x:
1. 
2. 
Then the solutions for
are:

To find the x intercepts of the graph
we have to replace with y=0.
This means: 
We already found the solutions for the expression, but we have to consider only the real solutions.

Because in a graph we can't have imaginary solutions.
Then the x intercepts of the graph are:
and 
The graph of the function is:
6²÷2(3) +4
36/2(3)+4
=(18)(3)+4
=54+4
=58
The answer is 25 add all the numbers together and divide by the number of numbers present hope this helped
Answer:
22.6
Step-by-step explanation:
a^2+b^2=c^2
8^2+b^2=24^2
b^2=512
b=22.6
