Ok, this is what you do,
7(^^^^^
84
7 goes into 8 1 time so it would be this
1
7(^^^^
84
- 7
and it leaves you with 14
1
7(^^^^
14
then how many time does 7 go into 14? 2 times
so it would be
12
7(^^^^
14
-14
AND YOUR ANSWER IS 12.

Step-by-step explanation:
If you factor the expression 7a+21 you can get:
7 × (a+3)
The are 8 blue bicycles, 6 green bicycles, and 4 yellow bicycles and total they equal 18.
Find the prime factorization
45=3*3*5
60=2*2*3*5
GCF=3*5=15
45=3*15
60=4*15
remember
ab+ac=a(b+c) so
45+60=15(3)+15(4)=15(3+4)=15(7)=105
