The greatest common factor (GCF) of 21 and 84 is 21.
The GCF is the largest number by which both numbers can be divided. Between 21 and 84, it is 21 because 21/21=1 and 84/21=4.
2+52=54
2+72=74 HOPE THIS HELPS :)
Shouldn’t it be 60? Think about it, six times the foot wide in in the paining plus 10 times the foot width on the wall
7.) Lets take 25/10 = 2.5
2.5 is the dilation
8.) Lets take 40/24 = 1.7
1.7 is the dilation
Hope this helps!
