To do this problem, you need to use the Pythagorean thermion I think.
Here is what I got as an answer
22.5 km
-9/3 + 4
-3 + 4 = 1
The answer to the question
You can double the product of 9 and 4 to get to the product of 9 and 8
x + (x + 3) +
= 75
so you will add up all of the x 's but NOT the x^2
2x + 3 +
= 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
