What is the difference of 21x / 3x^2 - 2 and 7 / 3x^2 - 2. show steps

Final answer is

Step-by-step explanation:

We have been given two terms

and

Now we need to find their difference. So let's subtract them

Denominators are equal so we can easily subtract numerators

We may factor the numerator but we won't get any factor in denominator that can be cancelled with numerator.

Hence final answer is

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

every 5 customers that walk in, only 2 buy popcorn.

step-by-step explanation:

basically 2/5.
