Answer:
6-x=-12
-x=-12-6
-x=-18
x=18
Step-by-step explanation:
subtract 6 from both sides becuse -6 is the oppiste of +6
6-6=0
-12-6= -18
then you divid -1x and -1 and
-1 and -18 because the x cant be a negative
[tex]n^{2} +3n-12=6[/tex]
Answer:
Step-by-step explanation:
n² + 3n - 18 = 0
n = [-3 ±√(3²-4(1)(-18)]/[2(1)] = [-3 ±√81]/2 = 3, -6
What is the simplest form of 4/10 in fractions
2/5 is the answer because you have to divided by 2 both
Answer: 2/5

2. Determine the slope of the line that passes through
the points (-1, -3) and (0, 6).
Answer:
9
Step-by-step explanation:
use the formula m = y2- y1 / x2 - x1
Answer:
Step-by-step explanation:
The slope of a line can be found using any two points of a line and the slope, m, is defined as
m=(y2-y1)/(x2-x1), we have points (-1,-3) and (0,6) so
m=(6-(-3))/(0-(-1))
m=9/1
m=9
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].

How does labeling the diagram help us show that we can use right triangle congruency (SAS in this case)?
Answer:
Step-by-step explanation:
S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.
If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle) the hypotenuse of the two triangles will be congruent.
Now, as hypotenuse and one leg are congruent in both triangles, we can apply RHS congruent
