Answer:

m = 5

Explanation:

Remark

This is a proportion question. A proportion is 2 equal ratios. There are 4 parts to a proportion. If 3 are known, the 4th can be found.

Formula

AB/AC = RQ/QS

Givens

AB = m

AC = 2

RQ = 10

QS = 4

Solution

m/2 = 10/4 Multiply both sides by 2

2m/2 = 2*10/4 Combine

m = 20/4

m = 5

Answer m = 5
