Answer:

(3x - 5)(x + 1)

Step-by-step explanation:

We need to factor 3x² - 2x - 5.

In order to do this, we must look at the factors of 3 and -5:

3 = 1 * 3

-5 = 1 * -5

Somehow, we need to pair up these so that they add to -2. We realize we can do this by multiplying 1 by -5 and adding that to 1 * 3:

1 * -5 + 1 * 3 = -5 + 3 = -2

So, we have (3x - 5)(x + 1).

Troyanec [42]

Answer:

D. y=70x

Step-by-step explanation:

The cheetah was clocked running 70 miles per hour.

i.e. in 1 hour cheetah covered 70 miles

in 2 hours cheetah covered 140 miles

in 3 hours cheetah covered 210 miles

in general, in n hour cheetah covered 70n miles

If y denote the distance covered

and x denotes the time cheetah runs

Then, y=70x

Hence, the equation which shows the relationship between the distance, y, and time, x, the cheetah runs is:

D  y=70x
