To solve this you can make a perportion
252 x
----- = -----
350 100
and solve 252 times 100/350=72
252 is 72% of 350
Count the distance d, which gives you 7.
Use Pythogarean theorem to find c:

Plug in the numbers:

c is 5.
Same thing with g:

g equals 5.66.

<h2 /><h2>Answer: 18</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />
First we need to substitute the value of the variable into the expression.
=
.
Now we need to solve
.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First, calculate 3 to the power of 2 and get 9.

Multiply 2 and 4 to get 8.
Subtract 5 from 8 to get 3.
Multiply 3 and 3 to get 9.
