Given: ab=12 ac=6 prove: c is the midpoint of ab

Step-by-step explanation:

Given : AB = 12 , AC = 6

To prove = AB = 2 × AC (C is mid point of AB)

Solution:

AB = 12...[1]

AC = 6.....[2]

[1] ÷ [2]

(hence, proved)

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.
