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

12) You can exchange $5 US dollars for L123 Honduran Lempiras. How many dollars can you exchange L2,300 for? ----​
Anit [1.1K]

Step-by-step explanation:

$5 US dollar = L123 Honduran Lempiras

L2300Honduran Lempiras = x ( Let $ be x)

By using chain rule, we get

5×2300 = 123×x

or, 11500 = 123x

or, x = 11500÷123

hence, x = 93.49593496
