Answer  10x - 15

Step-by-step explanation:

Because when you do the distributive property, you multiply the things in the parenthesis so 5 multiplied by 2x would be 10x and 5 multiplied by -3 would be -15. Hope this helps :)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
