Answer:
(3 - x)(3 + x)(2x + 1)
Step-by-step explanation:
18x - 2x³ + 9 - x² ( factor the first/second and third/fourth terms )
= 2x(9 - x²) + 1 (9 - x²) ← factor out (9 - x²) from each term
= (9 - x²(2x + 1) ← 9 - x² is a difference of squares a² - b² = (a - b)(a + b) )
= (3² - x²)(2x + 1)
= (3 - x)(3 + x)(2x + 1)
find the measure of the indicated angle
Answer:
∠ E = 57°
Step-by-step explanation:
Since DF = EF then the triangle is isosceles with 2 base angles congruent , so
∠ E = ∠ D = 4x + 1
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
4x + 1 + 4x + 1 + 5x - 4 = 180 , collect like terms
13x - 2 = 180 ( add 2 to both sides )
13x = 182 ( divide both sides by 13 )
x = 14
Then
∠ E = 4x + 1 = 4(14) + 1 = 56 + 1 = 57°

∘
340, degrees.
What is the length of the arc?
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answer:
length of arc ≈ 17.8 (to the nearest tenth)
Step-by-step explanation:
To find the length of the arc we use the formula for finding length of an arc.
length of arc = ∅/360 × 2πr
where
∅ = central angle
r = radius
∅ = 340°
r = 3
length of arc = ∅/360 × 2πr
length of arc = 340/360 × 2 × π × 3
length of arc = 340/360 × 6π
length of arc = 2040π/360
length of arc = 204π/36
length of arc = (204 × 3.14)/36
length of arc = 640.56/36
length of arc = 17.7933333
length of arc ≈ 17.8 (to the nearest tenth)

Step-by-step explanation:
let a, b, c represent the number of students in 6th, 7th, 8th grade
ratio of students : teachers = 28 : 1
There are 82 teachers , so 28 × 82 = 2296 students
Then
a + b + c = 2296 , that is
828 + b + c = 2296 ( subtract 828 from both sides )
b + c = 1468 → E

Find the x-intercept and y-intercept of the line.
4x + 5y = -20
-intercent:
10
Answer:
y-intercept is (0, -4)
x-intercept is (-5, 0)
Step-by-step explanation:
Remember the x-intercept and the y-intercept are the points on the graph where the line crosses the x-axis and the y-axis respectively.
We can find the x intercept and the y intercept a couple of ways. One way is to graph the line, which I will do later. The other way is to do a little math.
The equation of a line in y-intercept form is
[tex]y = mx + b[/tex]
where b = the y-intercept
In our equation above and solving for y we get the y-intercept is -4
[tex]4x + 5y = - 20 \\ 5y = - 4x - 20 \\ y = - \frac{4}{5} x - 4[/tex]
Doing more algebra and solving for x we get the x intercept is negative 5.
[tex]y = - \frac{4}{5} - 4 \\ y + 4 = - \frac{4}{5} x \\ x = - \frac{5}{4} y - \frac{20}{4 } \\ x = - \frac{5}{4} y - 5[/tex]
LM and N O are parallel lines what therom can we prove by translating the plane along the directed line segment M N?
Choose 1 answer:
When a traversal crosses parellel lines, alternate interior angles are congruent
When a transversal crosses any two lines, corresponding angles are congruent.
When a transversal crosses parallel lines, corresponding angles are congruent
When a transversal crosses any two lines, alternate interior angles are congruent.
Answer:
When a transversal crosses parallel lines, corresponding angles are congruent.
Step-by-step explanation:
When a transversal crosses parallel lines, corresponding angles are congruent can be used to prove that LM and NO are parallel lines
What is an angle?An angle is formed from the intersection of two or more lines. Types of angles are acute, obtuse and right angle.
If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.
Hence, When a transversal crosses parallel lines, corresponding angles are congruent can be used to prove that LM and NO are parallel lines

Circle the number in each row that is NOT a perfect square:
please help me!
Answer:
wdym?
Step-by-step explanation:
Answers:
First row = 3
Second row = 12
===================================================
Explanation:
Think of a square that has sides of 5 by 5. It's area will be 5*5 = 25. That means 25 is a perfect square.
We rule out 81 for similar reasons because 81 = 9*9
Also, 100 = 10*10 and 121 = 11*11
The only thing left is 3 which isn't a perfect square. We cannot multiply two of the same whole number to end up with an area of 3 square units.
Put another way, [tex]\sqrt{3}[/tex] is not a whole number while something like [tex]\sqrt{81} = 9[/tex] is a whole number.
This is all for the first row.
--------------------------
The second row is the same story.
4 = 2*2
9 = 3*3
144 = 12*12
36 = 6*6
This rules out everything but 12 in the second row. You can determine what is a perfect square through trial and error, or by memorizing what the perfect square numbers look like. With enough practice, they should be fairly memorized by some point.

The area of the parallelogram is given by the distance formula and the value of A = 13 square units
What is the distance between two points?Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )
The distance from A to B is the same as the distance from B to A
Distance between two points is the length of the line segment that connects the two points in a plane.
The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)
This formula is used to find the distance between any two points on a coordinate plane or x-y plane
Given data ,
Let the parallelogram be ABCD
Let the height of the parallelogram be AD
And , the base of the parallelogram be DC
where the area A = AD x DC
Now , the coordinates of A = A ( 3 , 6 )
The coordinates of D = ( 2 , 2 )
The coordinates of C = C ( 5 , 1 )
The distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)
So , the distance of AD = √ ( ( 3 - 2 )² + ( 6 - 2 )² )
The distance of AD = height of parallelogram AD = √17
And , the distance of DC = √ ( ( 2 - 5 )² + ( 2 - 1 )² )
So , the distance of DC = width of parallelogram DC = √10
And , area of parallelogram A = AD x DC = √17 x √10 = √170 units²
Hence , the area of parallelogram is A = 13 square units

Write the equation of the line in fully simplified slope intercept form
Answer:
y = 6x - 5
Step-by-step explanation:
In order to determine the slope-intercept form, y = mx + b, of the given line:
You need to find the slope (m) and determine the y-intercept (b).
Given the points (1, 1) and (0, -5):
Let (x1, y1) = (1, 1)
(x2, y2) = (0, -5)
Use the following formula for slope:
m = (y2 - y1)/(x2 - x1)
m = (-5 - 1)/(0 - 1)
m = -6/-1
m = 6
The slope of the line is 6.
Next, the y-coordinate (b) of the point, (0, b ) is the y-intercept of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
Looking at the graph, you'll see that the line crosses at point (0, -5). We used this point earlier to solve for the slope. Hence, the y-coordinate, b = -5, is the y-intercept.
Given the slope, m = 6, and the y-intercept, b = -5:
The linear equation in slope-intercept form is: y = 6x - 5.
