1 answer:

6 0

The correct answer is B) (2x-7)(x+4)=0. If you were to FOIL (First, Outer, Inner, Last) the answer, you would get 2x^2+1x-28=0.
Step by step:
(2x-7)(x+4)=0
FOIL it.
2x^2+8x-7x-28=0
Combine the two middle terms.
2x^2+1x-28=0
Move -28 and 1x over to the right side of the equation.
2x^2=28-x

Deon is riding his bicycle. He rides for 7 hours at a speed of 22.4 kilometers per hour. For how many kilometers does he ride

salantis [7]

By hypothesis, Deon is riding at a speed of 22.4 kilometers per hour. So each hour, he completes 22.4 km.

If he rides for 7 hours, he completes 22.4 * 7 = 156.8 km

So in 7 hours, he rides 156.8 kilometers.

Hope this helps! :)
