What is the negative GCF for-3x -18?
Debora [2.8K]

Answer:

-3

Step-by-step explanation:

GCF = greatest common factor

What is in common with 3x and 18? They are both multiples of 3.

3 times x = 3x

3 times 6 = 18

However, it is -3x and -18

So we can add a negative sign in front of the 3

Therefore, the GCF is -3.

Cheyenne ran a 5.6-kilometer race in 40 minutes. What was her speed in kilometers per hour? A. 224 B. 8.4 C. 7.1 D. 0.14
xz_007 [3.2K]
Hey there! :D

Let's find what Cheyenne runs in 10 minutes. 

Divide 5.6 by 4. 

5.6/4= 1.4

Multiply that by 6. (there are 60 minutes in an hour)

1.4*6= 8.4

"B" is the answer.

I hope this helps!
