Answer:
<h2>
Marianna is incorrect because x2</h2><h2>
2x13 can be factored into two binomials</h2>
Step-by-step explanation:
ax^2+bx+c = 0
x=−1+√14 or x=−1−√14
discriminant=56
completing square x=−1+√14 or x=−1−√14
Now, we can solve each term for
x=-2 she is incorrect
x(x+2)=0
Now, we can solve each term for
0:
x=0
- no other work needed,
and
x+2=0
x+2-2=0-2
x+0=-2
<u>x=-2</u>

Answer:
f(x) = -x^2 +8x -16
Step-by-step explanation:
With the given data, we can write the factored function as ...
f(x) = -1(x -4)^2 . . . . . -1 is the leading coefficient; exponent of 2 gives root multiplicity
f(x) = -x^2 +8x -16
The answer is $529, how I got my answer.
I multiplied $11.50×40=$460
then I multiplied 11.50×6=$69
then I added $460+$69=$529.
I hope this helps.
Answer: 30%
Step-by-step explanation:
It increased by 15 so it increased by 15/50=30/100=30%
I hope this helped!
