Answer:

378 miles

Step-by-step explanation:

<u>Remember that (rate)(distance) = time</u>

The train is going 90 mph for 3 hours. That's 270 miles in 3 hours.

Then you would multiply 72 (mph) by 1 1/2 (hours) and get 108 miles traveled in 1 1/2 hours.

Add those together and you get 378.

Answer:

17. a) (4x - 8)(6x+ 7); b) 20x - 2

18. a) (2x² + 3x - 5)(2x + 3); b) 4x² + 10x - 4

Step-by-step explanation:

Question 17

a) Area

Area = length × width

A = (4x - 8)(6x+ 7)

b) Perimeter

Perimeter = 2 (length + width)

P = 2(4x - 8 + 6x + 7) = 2(10x - 1) = 20x - 2

Question 18

a) Area

A = (2x² + 3x - 5)(2x + 3)

b) Perimeter

P = 2(2x² + 3x - 5 + 2x + 3) = 2(2x² + 5x - 2) = 4x² + 10x - 4
