This is just rearranging terms, it gets kind of ugly though. Start by dividing both sides by a to get D/a=2+kt, next move the 2 over to the left to get (D/a)-2=kt, finally divide the whole expression by t to get ((D/a)-2)/t=k

The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?
Ierofanga [76]

Do you have any more information? I can try to help :)
