Answer:
c
Step-by-step explanation:
the first one is x^2 + 6x + 34
the second one is x^2 - 12x + 37
the third one is x^2 + 16
If the ground beef is in pounds, it would be 5.25 lbs of ground beef.
We would get this answer by converting 3/4 into a decimal, .75. Then we multiply .75 by 7 (the number of people).
((This is if the amount of ground beef is in pounds, I'm not sure what it would be if it wasn't))
First, we can factor an x out of this.
We're left with x(x^2 - 16)
We can use the difference of squares theorem here to factor this further.
<h3><u>We're left with (x)(x + 4)(x - 4)</u></h3>
