Karris ran 8/18 of a kilometer and cycled 9/18 kilometers of a race. how many kilometers was the race in all?

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

1. what expression would be the same as 6x+x+0 2. find the prime factorization of 60 3. write the expression for 6 + x in words.

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
