Answer:
72 pi + 48 pi= 120pi (not sure if I am right tho)
Step-by-step explanation:
-2/9 is equal to -0.222222222 and it keeps on going hope it helps!
4/5 divided 8/7. You would do kcf or Kentucky chicken fried :) so you keep 4/5 multiply it by 7/8. Then multiply across and simplify. Hope this helps!!
Answer:
3:4
Step-by-step explanation:
4x=12
x=3
7y=28
y=4
First you need to factor the problems by using a couple of different methods, but the easiest could be the factor tree:
for example with 4-6a
you would put 4 = 2•2 so 2 is it’s GCF
and 6= 3•2 so 3 is it’s GCF
however the question is asking for the combined GCF (meaning the whole problem)
so 4-6a’s GCF would be 2 considering it is the only greatest common factor between BOTH numbers
for 12a^2 - 8a you would use the same method:
12a^2= 3a•2a•2 and 3a is it’s GCF
8a = 2•2•2a and 2a is it’s GCF
but combined, the greatest factor BOTH numbers have in common is 2a, so 2a is the answer!
i hope i helped you :)!❤️
