Julie wants to draw a triangle that is similar to a triangle on a coordinate plane. she choose to draw a triangle with sides that are proportional to the original triangle. which method could she use to draw a similar triangle? a. multiplying the x-values by 2 and the y-values by 2 b. multiplying the x-values by 2 and the y-values by 3 c. multiplying the y-values by 3 d. multiplying the x-values by 3

A

Step-by-step explanation:

In order to maintain the similarity for both x and y has to be amplified by the same ratio.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

so, converting firstly the mixed fractions to improper fractions and then "adding".
