Answer:
(x - 1)(x + 1)(x + 3).
Step-by-step explanation:
x^3 + 3x^2 - x - 3 Factor by grouping:
= x^2(x + 3) - 1(x + 3) x+3 is common .
= (x^2 - 1)(x + 3) x^2 - 1 is the difference of 2 squares.
= (x - 1)(x + 1)(x + 3).
Answer:
The answer is "Option a".
Step-by-step explanation:
please find the attached file.
In the given question, the positive correlation shows the scatterplot and, by adding six now higher calories, low-fat pasta, is the positive value for the new correlation of the coefficient will be decreasing.
In this question, the points are more close to the line and increasing from left to right, which can be mostly like, that's why the choice "a" is correct.
Answer: Alternative optimal
Step-by-step explanation:
Alternative optimal solution means that
there are several optimal solutions that can be used to get identical objective function value.
Therefore, a scenario whereby the optimal objective function contour line coincides with one of the binding constraint lines on the boundary of the feasible region will lead to alternative optimal solution.
