Define a polynomial that is a difference of squares. How do you know that it is the difference of squares? How is it factored?

Here you go, your equation should look a lot like this:

x²-16 > (x+4)(x-4).

Step-by-step explanation:

It's an example of what you should be writing depending on your answer. You did not include any details about your question.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

8121 because

130,000 divided by 16 is 8121
