A rectangle has area x3 + 3x2 - 18x in.2 and width x + 6 in. What is the length in inches?
Answer:
HOPE THIS HELPS
Step-by-step explanation:
The area = length * Width.
We know the width = X+6 inches and Area = x^3+3x^2–18x.
This problem can be solved just by dividing the area by width and we get a quotient as X^2–3x.
So the length is x^2–3x inches.
The length of the rectangle is [tex]\rm x(x-3)[/tex].
Given
The area of the rectangle = [tex]\rm x^3+3x^2-18x[/tex] square inches
The width of the rectangle = x + 6 inches
Area of the rectangleThe area of the rectangle is equal to the product of length and width of the rectangle.
Let the length of the rectangle be L.
The area of the rectangle is given by;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\\rm x^3+3x^2-18x= L \times (x+6)\\\\L=\dfrac{ x^3+3x^2-18x}{x+6}\\\\L = \dfrac{ x(x+6)(x-3)}{x+6}\\\\ L = x (x-3)[/tex]
Hence, the length of the rectangle is [tex]\rm x(x-3)[/tex].

Does this graph have any vertical asymptotes? If so, where?
Answer:
There are no vertical asympotes for this rational function.
Step-by-step explanation:
For rational functions, a vertical asymptote exists for every value of the independent variable such that function become undefined, that is, such that denominator is zero. Let be the following rational function:
[tex]C(p) = \frac{25000\cdot p}{100-p}[/tex], [tex]0\le p < 100[/tex]
There is a vertical asymptote for this case:
[tex]100-p = 0[/tex]
[tex]p = 100[/tex]
Which is out of the interval given to the rational function. Hence, we conclude that there are no vertical asympotes for this rational function.
Write the equation in slope-intercept form: 5x - 2y = 12
Answer:
Step-by-step explanation:
Solving
5x + -2y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
5x + -2y + 2y = 12 + 2y
Combine like terms: -2y + 2y = 0
5x + 0 = 12 + 2y
5x = 12 + 2y
Divide each side by '5'.
x = 2.4 + 0.4y
Simplifying
x = 2.4 + 0.4y
Solve the inequality: 5x + 7 < -23
Step-by-step explanation:
Given
5x + 7 < - 23
Subtracting 7 from both sides
5x + 7 - 7 < - 23 - 7
5x < - 30
Dividing both sides by 5
5x / 5 < - 30 / 5
x < - 6
Hope it will help :)
Answer: x = 14/5
Step-by-step explanation:
1. Add 7 to both sides.
5x=7 +7
5x=7+7
Simplify 7 +7 to 14
5x = 14
5x=14
Divide both sides by 5
x =14/5
x = 14/5
