11). 3x² -x    12). -5x + 5

Step-by-step explanation:

11). (4x² + x) - (x² + 2x)

4x² + x - x² - 2x

4x² - x² + x - 2x

3x² -x

12). (6x - 3) - (11x -8)

= 6x - 3 - 11x + 8

= 6x - 11x - 3 + 8

= -5x + 5  

the circle one

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to
