Answer:

<h2>G. 8m</h2>

Step-by-step explanation:

The perimeter of the given triangle:

(-x^2+3x+30)+(x^2-9)+(18-2x)=44

-x^2+3x+30+x^2-9+18-2x=44           <em>combine like terms</em>

(-x^2+x^2)+(3x-2x)+(30-9+18)=44

x+39=44           <em>subtract 39 from both sides</em>

x=5

The length of the shortes side:

18-2x=18-2(5)=18-10=8\ m

Ber [7]

The expression that can be used to represent the list price of the smartphone is 5179.99 * (1- 25%) and the value is 3884.9925

<h3>What expression can be used to represent the list price of the smartphone? </h3>
