Then figure out what the total cost of the trip would be.? We have to remember that instead of using the formula the way its written we have to order the steps differently, this order is C2 - B2 = A2. and does not matter since 8*1=8 and 1*8= 8. https://en.wikipedia.org/wiki/Pythagorean_theorem It states that the square of the hypotenuse [ https://en.wikipedia.org/wiki/Hypotenuse ] (the Pythagorean Theorem Calculator any 2 values below to solve the Pythagorean equation: a2 + b2 = c2. you square a (3^2=9=a) and b (4^2=16=b) and add the 2 values (9+16=25) to get to c. To complete the question, you have to square root c's value (square root of 25=5) because the formula says c^2 and not just c. Once you have done that, you can check your answer by squaring a,b and c to see if you have added and divided (Square-rooted) correctly. And when you ask them about algebra they think of solving equations. Actually, before I get my calculator out, let's just solve for a. So that is 9.
