Answer:
Step-by-step explanation:
92-8
The answer will be D I think that is the aswer
D and e are equivalent
if you plug in 1,2,3 for X for each equation you can see only d and e are equivalent to the original this is because (50/5)^x and 50^x/5^x simplified is still 10^x
1st he should have found the GCF of 60
2nd he should have found the GCF of 90,
the GCF of 30 = 2x3x5
the GCF of 90 = 2x3²x5
So the GCF of 60 and 90 is 2x3x5 = 30
