Since supplementary angles are angles that equal to 180, you first need to subtract 40 from 180 to find out what the equation equals. This is the layout of the equation. 140=4x+20. Next you subtract 20 from each side, 120=4x then you divide by 4 four, x=30.
        
                    
             
        
        
        
I'm guessing you mean

First, compute the quotient:

Split up the remainder term into partial fractions. Notice that
<em>x</em> ² + 4<em>x</em> + 3 = (<em>x</em> + 3) (<em>x</em> + 1)
Then

So the integral becomes

We can simplify the result somewhat:

Answer:
18 cups.
Step-by-step explanation:
We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation:  .
.
To find number of cups x to make a profit of at least  $20 we will use our given inequality.






Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.
