Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots

Explanation:
Let's look at the 3 sandwiches and 3 soups first and then expand the calculation. There are 9 ways I can have one of the sandwiches and 1 of the soups:
⎛

⎜

Soup 1
Soup 2
Soup 3

And so we can see that we multiply the number of sandwiches and the number of soups to get the total number of ways to get one of each.
The same works for more categories of choices, and so we multiply the 3 sandwiches, the 3 soups, 4 salads, and 2 drinks to get:

<h2><u>In total, she will need $98.34 to pay all of the foods she plans to serve at the party.</u></h2>
All of the work:
<em>How to solve the amount of pizza she needs:</em>
20 x 3 = 60
60 divided by 10 = 6
<em>How to solve the amount of soda bottled needed:</em>
20 x 16 = 320
320 divided by 64 = 5
<em>How to solve the number of pans she needs:</em>
20(2 x 3) = 40 x 60
40 x 60 divided by 8 x 12 = 5
<h2>
THE COST CAN BE FOUND BY MULTIPLYING THE NUMBER OF THE ITEM NEEDED AND THE PRICE FOR EACH OF THE ITEM.</h2>
<em>Number of pizza she needs:6 pizza, costs $77.94</em>
<em>Number of soda bottles she needs:5 bottles, costs $8.45</em>
<em>Number of pans she needs:5 pans, costs $11.95</em>
<em>Add 77.94, 8.45, and 11.95 and get 98.34</em>
Are there choices? I would say 4x1x3, or 12 options after the color is chosen.
