Answer:
Step-by-step explanation: We have been given 4 expressions. We are asked to choose the expression that represents sum of cubes.
We know that sum of cubes is in form .
We can see that 1st and 2nd option has a negative sign. Therefore, these options cannot be sum of cubes.
Let us check 3rd and 4th options one by one.
We can rewrite our expression by writing terms as cubes:
Therefore, expression is a sum of cubes.
In 4th expression, we can see that . We cannot represent it as a cube. Similarly, we cannot represent as a cube. Therefore, 4th expression is not correct.
The other two linear factors of the polynomial x³ + 4x² +x -6 are; Choice A: (x – 1) and (x + 3)
<h3>Polynomial division</h3>
By ling division of polynomials, it follows that the division of polynomial x³ + 4x² +x -6 by x +2 yields the quadratic expression;
On this note, the factorisation of the quadratic expression above yields factors;

Answer:
5610
Step-by-step explanation:
unaffected people will be (100%-2.5\%-50.75%)=46.75% of 12000:

First, put the equations into slope-intercept form(y = mx + b):

Since slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept, the slope of the line(value of m) determines whether the lines are parallel or perpendicular.
Parallel lines have the same slope, and since

, the lines are parallel. Also, because the m's aren't the same, the lines aren't identical.
Your answer is
parallel.
Answer:
approximately 21484
Step-by-step explanation:
Volume= 4/3 pi r^3
30001= 4/3 pi r^3
solve for r to get 41.34747142
Then, use surface area formula
SA= 4pi r^2
SA=4pi(41.34747142)^2
SA= 21483.6355
