1. Use the FOIL method (x+9)(x+9)
First, outer, inner, last
$x^{2} +9x+9x+81$
Add your like terms
$x^{2} +18x+81$

2. When you add or subtract polynomials you add or subtract the like terms and then put them in order from largest to smallest exponents.

3. $-5x(5 x^{3} +10 x^{2} -6x+3)$

4. Since it is the perimeter, we add the 3 together.
$(2 x^{2} +4x-3)+(-3 x^{2} -3)+(5x+19)$
Add the like terms together:
$2 x^{2} +(-3 x^{2} )=- x^{2} \\ 4x+5x=9x \\ -8+(-3)+19=8$
Put them in order of exponents
$- x^{2} +9x+8$

Hope this helps

4. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price.
