Answer:
See explanation below.
Step-by-step explanation:
No. 22:
Area of new garden [tex]= 22x-x^2[/tex] + Area of new plot
[tex]=22x-x^2+(8\times 6)\\\\=22x-x^2+48\:\:square \:feet[/tex]
is the required polynomial expression representing the new area.
No. 24:
Let's say length of the table is [tex]x[/tex].
Width of the table [tex]= x-24[/tex]
After adding the tablecloth of 6 inches the new dimension are:
Length = [tex]x+12[/tex]
Width = [tex]x-24+12 = x-12[/tex]
Now, perimeter = 2(Length + Width)
[tex]=2(x+12+x-12)\\\\=2(2x)\\\\=4x[/tex]
