Answer:

1.x^2

2.x+8

3.x

4. 8x

Step-by-step explanation:

Length of old is x inches.

Because it is square we have that area of the old canvas : [tex]x^2[/tex]

When we read : width of new is increased by 8 so : x+8

Length is x.

The difference of areas:

Old canvas : A1=[tex]x^2[/tex]

New canvas : [tex]A2=x(x+8)=x^2+8x[/tex]

Now we can find A2-A1:

[tex]x^2+8x-x^2=8x[/tex]
