Answer:
C) 20x+78
Step-by-step explanation:
9(x-6)+11(x+12)
9x-54+11x+132
20x-54+132
20x+78
We have equation:

p = number of phones left to repair
108 = initial amount at the start of week
23 = number of phones repaired each day
d = number of days she worked that week
This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.
<h3>Greatest common factor</h3>
Given the following expression
32ab - 8
Find the factors of each terms
32ab = 8 * 4. * a * b
8 = 8 * 1
Since 8 is common to both factors, hence
32ab - 8 = 8(4ab -1)
This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.
