Answer:
There are 2 red pens in each pack
There are 3 blue pens in each pack
Step-by-step explanation:
<u> we know that</u>
270=2*3^{3} *5
180=2^{2}*3^{2}*5
<u>Find the Greatest Common Factor (GCF)</u>
The GCF is equal to------> 2*3^{2}*5=90
the greatest number of packs she can make is 90
Find the number of red pens in each pack 180/90=2 red pens
Divide the total number of red pens by the total number of packs
Find the number of blue pens in each pack 270/90=3 blue pens
Divide the total number of blue pens by the total number of packs

Answer:
6b+b^2 (b to the 2nd power)
Step-by-step explanation:
8b+b^2-2b (b to the 2nd power)
(8b-2b)+b^2
6b+b^2
Hopefully this helps :)
