Answer:
1
Step-by-step explanation:
GCF(18, a, 20ab) = 1
18 and <em>a</em> do not necessarily have any factor in common, so their GCF is 1. Adding more terms to the list will not increase the GCF beyond that value.
Answer:
x=11
Step-by-step explanation:
You have to isolate the x term; to do this you subtract 13 from the x+13 and the 24. By subtracting 13 from 13, it cancels out the 13 and 24-13=11
