(b) After his first month he had more than he expected to have due to interest the bank provided. This let w
Rob come up with a better expression, +45w+135, where w is the number of weeks. How much
25
will he have in 1 year?

207/8 is the right

it will take 9 minutes                

using the formula for pythagorean theorem (a2+b2=c2)(the twos are exponents), and knowing that you have b squared and c squared, just reverse it. 26 squared minus 10 squared equals c squared. 26 squared is 676 and 10 squared is 100. you get 576, then use your square roots to undo the squared numbers to get 24.
