Answer: $$x(x+4)(x+3)=x(x^2+7x+12)=x^3+7x^2+12x$$.
Step-by-step explanation:
In general, if you want
x
=
c
to be a root of a polynomial, then the polynomial must contain at least one factor of the form
x
−
c
(if
c
<
0
the
x
−
c
can be written as an addition of a positive number).
The first question is the 3rd choice.
The second question is also the 3rd choice.

Answer: 5
Step-by-step explanation:
Y-intercept is of the graph is 0
Answer:
x - ( 2 + 1 1/3)
=x- 3 1/3
- 3 1/3 feet
The water level of a pond falls 3 1/3 feet below its normal level.
Step-by-step explanation:
The water level of a pond is 2 feet below its normal level.
The water level of the pond dropped another 1 1/3 feet.
So the total level dropped is 2 + 1 1/3
= 2 + 4/3
= 6+4/3= 10/3 = 3 1/3 feet below the normal.
Suppose the normal is at zero then the level of the pond is at the end of the summer is 0 - 3 1/3 = - 3 1/3 feet.
If we represent the normal by x then the equation becomes
x- 3 1/3 feet to show the water level at the end of summer.
Or it can also be written as
x - ( 2 + 1 1/3)
