3. If Triangle MNP - Triangle QRS, MN = 14, NP = 8 MP=16 and QS = 7 then which of the following could be used to
solve for the length of QR ?

(4) QR/7 = 14/16

Explanation:

Given that Triangle MNP is similar Triangle QRS, then MN is proportional to QR, NP is proportional to RS, and MP is proportional to QS.

This proportions can be written as follows:

QR = k*MN or k = QR/MN = QR/14

RS = k*NP or k = RS/NP = RS/8

QS = k*MP or k = QS/MP = 7/16

where k is some constant. Therefore:

QR/14 = 7/16 or QR/7 = 14/16

if you break down the data from the global footprint network, china exerts far more pressure on its ecosystems per capita than america in terms of crops, grazing, foresting, and fishing. but where america blows everybody out of the water is carbon emissions per capita
