Question 940916
.A___________________.M___________________.B

AM= 2x+4
MB= 5x-8
AB= ?

So to get AB, you would need to find the total measurements of AM and MB.

AM=MB

2x+4=5x-8
2x=5x-12
-3x=-12
_______________
x=4



So now to find the measurement of AB, you need to plug it into AM and MB.


2(4)+4+5(4)-8= 24!!!




So the measure of AB would be 24.
