Question

A car company tested a sports car on a road with different inclines. The test driver tested the car by driving a distance of x miles on a flat road, (x^2 + 3) miles downhill, and (x - 7) miles uphill. Which simplified expression is equivalent to the total distance, in miles, for which the car was tested?

3x^2 - 4
3x^2 + 10
x^2 + 2x - 4
x^2 + 2x + 10

Give me a second to write out my answer

Answer 1

(x^2 + 3) + (x - 7)

x^2 + 3 + x - 7

x^2 + x - 4

Answer 2

you left one x out

Answer 3

- the distance he drove on the flat

Answer 4

Oh, so it's x^2 + 2x - 4

Answer 5

Right :)

Answer 6

yes
