Answer 1

Answer:

Step-by-step explanation:

Given:

AC = 32

AB = 2x

BC = 6x+8

A. segment addition postulate:

Segment Addition Postulate states that given points A and C, a third point B lies on the line segment AC if their distances between the points satisfy the expression:

AB + BC = AC.

B. substitution

This property allows you to substitute quantities for each other into an expression as long as those quantities are equal.

2x + 6x + 8 = 32

C. Simplification property of equality

Adding the like variables together on each side of the equality.

8x + 8 = 32

D. Subtraction property of equality

This involves subtracting the same value on both sides of the equality.

8x + 8 - 8 = 32 - 8

8x = 24

E. Division property of equality

Dividing both sides of the equality with a non zero value.

8x/8 = 32/8

x = 3
