Answer:
6y^2+2y
Step by step explanation:
2y*(y+3)+4y*(y-1)
Distribute 2y through the parentheses
2y^2+6y+4y*(y-1)
Distribute 4y through the parentheses
2y^2+6y+4y^2-4y
Collect like terms
6y^2+6y-4y
Collect like terms
6y^2+2y
Answer
6y^2+2y
The exact answer would be 3218.69 meters but since you're rounding upwards, your answer would be D. 3,220 meters.

There are 21 red pens. For every 3 red pens, there is 1 blue pen.
Let's make these into a fraction equation.
21/p=3/1
p is the number of blue pens we have yet to find.
First, cross multiply.
21x1=21
px3=3p
Now, we have an equation of
21÷3p
We set it equal to 1, and we solve it.
21÷3p = 1
(21÷3p)×3p=1×3p
21=3p
21÷3=(3p)÷3
7=p
So, if there are 21 red pens, there are 7 blue pens.
We add these together to find the total number of pens the teacher has.
21+7=28
The teacher has 28 pens total.
