According to the question, we are to complete a 2-column proof to show that the measure of BC is equal to EF:
Given the following:
AC = AB + BC....................... 1
AC = AB + x ............... 2
From equation 2, AB = AC - x ................. 3
Substitute equation 3 into 1:
AC = AB + BC
AC = AC-x + BC
AC-AC = -c + BC
0 = -x + BC
BC = x
Since AC is greater than AB by a value of x, hence AC > BC

Answer:
2996
Step-by-step explanation:
5x + 4x = 6741
9x = 6741
x = 6741/9
x = 749
to get the no votes,
4x i.e 4*749
=> 4*749 = 2996
hope this helps :)
