Segments & Distance

Choose the correct form of the distance formula.

If A(3,1) and B(-2,-1) then the correct equation to find AB is:

Find ST if S is between R and T, SR = 2x + 7, ST = x - 6, and RT = 100

• 74

• 99

• 27

• 33

Find DF if D is between E and F, ED = 6x - 4, DF = 3x + 5, and

EF = 46.

• 20

• 22

• 26

• 28

Find the distance between C (-5, 4) and Q (2, 0).

To the nearest tenth, find the distance between D(3, 24) and E(7, 56).

• DE = 32.1

• DE = 32.2

• DE = 32.4

• DE = 33.2

If E is between D and F, DE = 47, EF = 3x + 10 and DF = 9x - 39, find EF.

• EF = 19

• EF = 34.5

• EF = 58

• EF = 38.7

To the nearest tenth, find the distance between L(-5, -8) and M(-1, -16).

• LM = 8.9

• LM = 9.8

• LM = 10.3

• LM = 11.0
