Answer:

Step-by-step explanation:
we know that
The roots of the polynomial are the values of x when the value of the polynomial f(x) is equal to zero
The roots of the polynomial function are
x=-6 -----> (x+6)=0
x=-5 -----> (x+5)=0
x=-1 -----> (x+1)=0
The equation of the cubic polynomial is

where
a is the leading coefficient
Remember that
f(0)=60
That means ------> For x=0 the value of f(x) is equal to 60
substitute the value of x and the value of y in the function and solve for a




so

Applying the distributive property
Convert to expanded form

$62 is both numbers added together
Answer: The reason why this is the answer is because 4 out of 20 (4/20) is 0.2, so 16 out of 20 (16/20) is 0.8
