Answer 1

See explanation below.

Explanation:

No. 22:

Area of new garden
`= 22x-x^2` + Area of new plot

`=22x-x^2+(8* 6)\\\\=22x-x^2+48\:\:square \:feet`

is the required polynomial expression representing the new area.

No. 24:

Let's say length of the table is
`x`.

Width of the table
`= x-24`

After adding the tablecloth of 6 inches the new dimension are:

Length =
`x+12`

Width =
`x-24+12 = x-12`

Now, perimeter = 2(Length + Width)

`=2(x+12+x-12)\\\\=2(2x)\\\\=4x`
