5(c). 6.5 centimeters

5(d). 1 and 1/2, or 1.5 inches

5. x = 4

6. No, they are not collinear. If they were collinear, AB + BC would have to equal the value of AC.

Black_prince [1.1K]

Answer:

A) Associative Property of Addition

Step-by-step explanation:

<u><em>Associative Property of Addition</em></u>

Let A, B and C  be any three real numbers

A+(B+C) = (A+B) + C

Given data

(20.4 + 3.75) + 4.25 =  20.4 + (3.75 + 4.25)

                                 =  20.4 + 8.0

                                =  28.4
