Answer:

$\large\boxed{\dfrac{m^8}{25}}$

Asa has 4 colored pencils. His friend purchases three times as many. If Asa’s friend buys two more 4-packs, which expression sho

daser333 [38]

Three times as many as four - 3(4) / 4*3/ 4+4+4

4 x 3 = 12

Then for 2 more 4 packs, it'd be 8 since it's either 2*4 or 4+4 (both equal eight)

And then you'd add them both together, 12+8=20

But since it's asking for both Asa and his friend's total amount, you'd add four more to it since 20 is just his friend's amount.
