Answer:
[tex]\frac{x^3 + x^2 -20x + 24}{x-3} = x^2 +4x-8[/tex]
Step-by-step explanation:

What is the least common denominator (LCD) of 12 and 23?
5
6
12
18
Answer: none of those, 276...?
Step-by-step explanation:
You need to know the least common denominator (LCD) of 12 and 23 if you want to add or subtract two fractions with 12 and 23 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 12 and 23 is 276.
Here is a math problem example where you need to know the LCD of 12 and 23 to solve:
3/12 + 2/23 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
276/12 = 23
276/23 = 12
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 23 = 69
2 x 12 = 24
Step 3) Put it all together to solve the problem:
69/276 + 24/276 = 93/276
= 3/12 + 2/23 = 93/276
It's that easy! Once again, the lowest common denominator (LCD) of 12 and 23 is as follows:
276

The answer would be x = -3
That forms the straight line at the x = -3 point
The diagonals of kite ABCD intersect at E. If ∡EBC=30°, what is ∡BCE?
Answer:
∡BCE = 60
Step-by-step explanation:
Here, we want to find the angle marked BCE
From our diagram, the angle marked BCE is y
Looking at triangle BCE, we have the right angle, an angle measure of 30 and the angle marked y which we say is BCE
mathematically, the sum of all these will give 180 as the sum f the interior angles of a triangle is 180
Thus, we have that;
y + 30 + 90 = 180
y = 180-120
y = 60
Write an equation for the line in standard form
Answer:
The equation of the line in standard form is y = -1/2·x - 3
Step-by-step explanation:
From the given graph, the "x" and "y" coordinates points through which the line of the graph passes are;
(-4, -1), (-2, -2), and (2, -4)
The slope, m, of the graph is given as follow;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, by substituting the values of the coordinates for two known points, we have;
[tex]Slope, \, m =\dfrac{(-4) -(-1)}{2-(-4)} = \dfrac{(-4) + 1}{2+4 } = \dfrac{-3}{6} = -\dfrac{1}{2}[/tex]
The slope of the graph, m = -1/2
The equation of the graph on point and slope form is given as follows;
y - (-4) = -1/2(x - 2)
y = -x/2 + 1 - 4 = -x/2 - 3
The equation of the line in standard form, y = m·x + c is y = -1/2·x - 3.

The price of an item has been reduced by 20%. The original price was $55. What is the price of the item now?
Answer:
The price is now $44
Step-by-step explanation:
The original price is $55
The discount percent is20%
Calculate the savings: 20% of $55 = $11
Subtract the savings from the original price to get the sale price: $55 - $11 = $44
Find 0.3% of 60.
help pleaseee
0.3 percent of 60 is 0.18.
To find 0.3 % of 60, we can convert 0.3 % to decimal form by dividing it by 100: 0.3 ÷ 100 = 0.003.
Next, we multiply 0.003 by 60 to calculate the desired percentage:
0.003 * 60 = 0.18.
Therefore, 0.3% of 60 is 0.18. This means that if we take 0.3% (0.003) of the value 60, the result is 0.18. It can also be interpreted as 0.18 being 0.3% of 60. By converting the percentage to decimal form and multiplying it by the given value, we obtain the corresponding portion or fraction of the whole.

HELP ASAP!!! HELP PLS!!
Answer:
It is D ................
Answer:
The [tex]\mathbf{Slope=\frac{1}{4}}[/tex]
The y-intercept is (0,3)
Option D is correct.
Step-by-step explanation:
A linear function given has following points:
x y
-8 1
0 3
We need to find slope and y-intercept
To find slope, we can use formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have x_1=-8, y_1=1, x_2=0, y_2=3
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{3-1}{0-(-8)}\\Slope=\frac{3-1}{0+8}\\Slope=\frac{2}{8}\\Slope=\frac{1}{4}[/tex]
So, we get [tex]\mathbf{Slope=\frac{1}{4}}[/tex]
We need to find y-intercept.
y-intercept can be found by putting x =0.
Looking at the table, when x =0, y=3
So, y-intercept is (0,3)
The required answer is:
The [tex]\mathbf{Slope=\frac{1}{4}}[/tex]
The y-intercept is (0,3)
Option D is correct.

ABC congruent DEF find the measure of the given angles or the lengths of the given sides
Answer:
BC = 8 and EF = 8
Step-by-step explanation:
Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.
Let us solve the question
∵ The two triangles ABC and DEF are congruent
∴ BC = EF
∵ BC = 3z + 2
∵ EF = z + 6
→ Equate their length
∴ 3z + 2 = z + 6
→ Subtract z from both sides
∵ 3z - z + 2 = z - z + 6
∴ 2z + 2 = 6
→ Subtract 2 from both sides
∵ 2z + 2 - 2 = 6 - 2
∴ 2z = 4
→ Divide both sides by 2
∴ z = 2
→ Substitute z by 2 in the length of sides BC and EF to find them
∵ BC = 3(2) + 2 = 6 + 2
∴ BC = 8
∵ EF = 2 + 6
∴ EF = 8
