Which simplified expression can be used to find the difference in the number of miles between Tom's route and Julio's route?

Answer 1

Answer 3

Tom's route has a distance

\[2x^2 -1 + 3x + 5 \]

you need to simplify this my collecting like terms

Julio's route has a distance

\[2x^2 + 7\]

the difference in the lengths is found by subtracting Tom - Julio

\[2x^2 + 3x + 4 -(2x^2 + 7) = ?\]

distribute the -1 infront of the brackets and then collect like terms.

Answer 4

3x-3?

Answer 5

that's correct

Answer 6

awesome thanks
