Answer:
P(x) = -5(x² - 12)² + 405
Step-by-step explanation:
P(x) = -5x² + 120x - 315
Factor out -5 from the first two terms
P(x) = -5(x² - 24x) - 315
Complete the square
P(x) = -5(x - 12)² - (-5(-12)²) -315
P(x) = -5(x - 12)² + 720 - 315
P(x) = -5(x - 12)² + 405
(4 3/8) + (5 1/3)
(4+5)(3/8 + 1/3)
9 + (17/24)
she ran 9 17/24 miles total
<u>Half</u> of 4.50 is 2.25, so for <u>one</u> pound it would be <u>$2.25</u>.
To calculate five pounds, you need to add 2.25+2.25+2.25+2.25+2.25 = <u>11.25</u>.
For <u>five</u> pounds of strawberry's, it would cost <u>$11.25</u>.

Answer: 
Step-by-step explanation:
We can use the Rational Root Test.
Given a polynomial in the form:
Where:
- The coefficients are integers.
- 
is the leading coeffcient (
)
- 
is the constant term 
Every rational root of the polynomial is in the form:
For the case of the given polynomial:
We can observe that:
- Its constant term is 6, with factors 1, 2 and 3.
- Its leading coefficient is 2, with factors 1 and 2.
Then, by Rational Roots Test we get the possible rational roots of this polynomial:
