1. A rectangle has side lengths of 3r2 + 5x - 1 and -7x +1. Which of the following expressions represents the area of the rectangle?

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

i belive those are the ones that are under 90 degreese.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
