Answer:

Step-by-step explanation:
64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
Answer:
a) y = 5x
b) y = 60
Step-by-step explanation:

So, 12*5 = 60.
