Answer:
A-2
B
Step-by-step explanation:
(1 / 5) hour is 12 minutes and five times this equals 1 hour.
So the distance times 5 equals miles per hour.
(3 / 4) * 5 = 15 / 4 = 3.75 mph
3x(5x+6)-8(1+8x)
15x^2+18x-8-64x
15x^2-46x-8 is your final answer
(5b^2 - 3b + 2) + (2b - 4)
Just expand out all the brackets
5b^2 - b - 2
