Answer:
125
Step-by-step explanation:
We are given that a pencil company produces two types of pencils
Mechanical pencils and wooden pencils.
In 40 packages of each type , number of packages of wooden pencils which have incorrect weight=5
We have to find the number of packages in 1000 packages of each type have incorrect weight.
In 40 packages of each type of pencil , number of packages have incorrec weight=5
In 1 package of each type of pencil , number of packages have incorrect weight=\frac{5}{40}[/tex]
In 1000 of each type of pencil , number of packages have incorrect weight=
Hence, 125 packages have incorrect weight when the company check 1000 packages of each type.

Answer:
A. 2x(x+1)(x-6); 0, -1, 6
Step-by-step explanation:
The zeros are the values of x that make the factors zero. That is, for binomial factors, they are the opposite of the constant in the binomial factor. For example, the factor (x+1) will be zero when x = -1, so that -1+1 = 0.
This observation eliminates choices B and C.
__
The product of binomial factors looks like this:
(x +a)(x +b) = x² +(a+b)x +ab . . . . . x-coefficient is (a+b)
Once 2x is factored from the given polynomial, the resulting quadratic is ...
x^2 -5x -6
This means the sum of the constants in the binomial terms must be -5. That will only be the case for choice A.
