The product of 4xy and y² + 2x can also be written as
4xy(y² + 2x)

When we have brackets like this, we multiply whatever is left of the brackets by everything inside.

1) 4xy multiplied by y²
    4xy x y² = 4xy³

2) 4xy multiplied by 2x
    4xy x 2x = 8x²y

3) Add together 4xy³ and 8x²y
    4xy³ + 8x²y

Alex Ar [27]

Answer:

Step-by-step explanation:

We are given that Jenna knits scarves and sells them on Etsy an online market place.

$C(x)=4x+20$

Where C=Represents the cost in dollars

x=Number of scarves

We have to create a table to show the relationship between the number of scarves x and the cost C

Substitute x=1

$C(1)=4(1)+20=$ $24

Substitute x=2

$C(2)=4(2)+20=$ $28

$C(3)=4(3)+20=$ $32

$C(4)=4(4)+20=$ $36

$C(5)=4(5)+20=$ $40

$C(6)=4(6)+20=$ $44
