D. 4.0 geometry math question no guessing and show work

x=3.5

This is how I did it I took the bottom 2, 3 and 2.4 and I divided 3 by 2.4 (3/2.4) and got 1.25. I then multiplied 2.8 by 1.25 and found that x was 3.5

Answer is C. 3.5

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

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
