Step-by-step explanation:
Given as :
On the checkerboard , The fraction of red pieces left = 
Let The fraction of black pieces left = x
So, The fraction of black pieces left = x = 1 -
Or, x = 
Or, x =
Hence The fraction of black pieces left is Answer
Polynomials are equations that uses variables and several terms
The polynomial in standard form is f(x) = x^2 - x -20
<h3>How to determine the polynomial</h3>
The polynomial has 2 zeros.
So, the form of the polynomial is:
f(x) = a(x - x1)(x - x2)
The zeros of the polynomial are 5 and -4.
So, the equation becomes
f(x) = a(x - 5)(x + 4)
The value of a = 1.
So, we have;
f(x) = 1(x - 5)(x + 4)
This gives
f(x) = (x - 5)(x + 4)
Expand
f(x) = x^2 - x -20
Hence, the polynomial in standard form is f(x) = x^2 - x -20

Answer:
10.5 hours
Step-by-step explanation:
To find the number of hours she babysat last week subtract 5 from 11 which is 7 hours. 7 hours is equal to 2/3 of the many hours. If she babysat h hours last week then solve for h using 2/3 h = 7.
Solve the equation by multiplying each side by the reciprocal.
3/2 * 2/3h = 7*3/2
h = 21/2
h = 10.5 hours
