Question

What is the value of x? Justify each step.
AC=32
2x 6x+8
.__________________._________________.
A B C
Drawing not to scale

AB + BC = AC a.__________________________
2x+6x + 8 =32 b. __________________________
8x + 8 =32 c. __________________________
8x =24 d. __________________________
X =3 e. __________________________

Answer 1

A represents segment addition postulate which states that if B is between A and C, then AB + BC = AC

Answer 2

Is B between A and C?

Answer 3

in the drawing you did above? Yes, B is between A and C and AC=32, so that means AB and BC equals half of 32. AB+BC=AC

Answer 4

i understand it is not multiple choice question, they want you to state what properties and methods used to solve the equation

Answer 5

for the very first one just state segment addition postulate and i already described how this method is used

Answer 6

@Zale101 I don't know anything about this

Answer 7

take a look at this description: http://en.wikipedia.org/wiki/Segment_addition_postulate

Answer 8

ok

Answer 10

the equation is already solved. All you have to do is Justify each step as its written in your question. X=3, the value of X is therefore solved :)

Answer 11

put Segment addition postulate

Answer 12

what's confusing you?

Answer 13

ok if they asking the steps how do he word it. I feel like he could put anything and it will be right in my eyes cause I don't know it

Answer 14

I graduated high school years ago I don't remember non of this
