Answer:
x = -10
Step-by-step explanation:
1) A line creates a 180° angle on each side of it. Even if another line intersects it, we know that the total measure of angles on that side will equal 180°.
2) We set the equations equal to 180.
(-4x) + (-14x) = 180
Combine like-terms
-18x = 180
Isolate x by dividing both sides by -18.
x = -10
3) To solve for each angle, you can plug in -10 for x and solve.
-4(-10) = 40°
-14(-10) = 140°

Step-by-step explanation:
Given expression is [tex]\frac{-5x^3+2x^2+9x+2}{(x^2+2)^2}[/tex]
Option A
[tex]\frac{A}{x^2+2}+ \frac{Bx+C}{(x^2+2)^2}[/tex]
= [tex]\frac{A(x^2+2)}{(x^2+2)^2}+ \frac{Bx+C}{(x^2+2)^2}[/tex]
= [tex]\frac{Ax^2+2A+Bx+C}{(x^2+2)^2}[/tex]
Numerator is a quadratic polynomial, while the expression has the numerator as a cubic .
Therefore, both the expressions are not equivalent.
Option B
[tex]\frac{A}{(x^2+2)^2}+ \frac{Bx+C}{(x^2+2)^2}[/tex]
= [tex]\frac{A+Bx+C}{(x^2+2)^2}[/tex]
Here, numerator of the expression is a linear polynomial which is not equal to given expression.
Therefore, both the expressions are not equivalent.
Option C
[tex]\frac{Ax+B}{(x^2+2)}+ \frac{Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{(Ax+B)(x^2+2)}{(x^2+2)^2}+ \frac{Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{Ax^3+Bx^2+2Ax+2B+Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{Ax^3+Bx^2+x(2A+C)+D}{(x^2+2)^2}[/tex]
Here, numerator is a cubic polynomial.
Therefore, both the expressions are equivalent.
Option D
[tex]\frac{Ax+B}{(x^2+2)^2}+ \frac{Cx+D}{(x^2+2)^2}[/tex]
= [tex]\frac{x(A+C)+(B+D)}{(x^2+2)^2}[/tex]
Numerator is a linear polynomial.
Therefore, sum is not equal to the given expression.
Option C will be the answer.

A circle has a diameter of 3 meters. Which statement about the circumference and area is true?
A comparison of the area and circumference is not possible since the area cannot be determined
The numerical value of the circumference and area are equal.
The numerical value of the circumference is greater than the numerical value of the area.
O The numerical value of the circumference is less than the numerical value of the area.
Answers
Answer:
The numerical value of the circumference is greater than the numerical value of the area.
Step-by-step explanation:
Diameter = 3 meters
The radius is half of diameter so,
Radius = 3 ÷ 2 = 1.5 meters
Circumference = 2πr (r is the radius)
= 2 x π x 1.5 = 9.42 meters (rounded to 3 significant figures)
Area of a circle = π[tex]r^{2}[/tex]
= π x [tex]1.5^{2}[/tex]
= π x 2.25 = 7.06 meters
The true statement is
The numerical value of the circumference is greater than the numerical value of the area.
What is Area and Circumference?The space a circle takes up in a two-dimensional plane is known as the area of the circle.
The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.
we have,
Diameter = 3 m
Radius= D/2 = 3/2 m
So, Area of Circle
= πr²
= 3.14 x 3/2 x 3/2
= 7.065 m²
and, Circumference of circle
= 2πr
= 2 x 3.14 x 3/2
= 9.42 m
Thus, The numerical value of the circumference is greater than the numerical value of the area.

The seventh-grade class is putting on a variety show to raise money. It costs $150 to rent the auditorium that they are going to use. If they charge $5 per ticket, how many tickets do they need to see in order to raise at least $750?
Answers
Answer:
180 tickets
Step-by-step explanation:
750 + 150 = 900 they will have to make
900/5 = 180 tickets
To raise at least $750, the seventh-grade class needs to sell a minimum of 180 tickets, priced at $5 each, to cover the fundraising goal and the $150 auditorium rental cost.
Given that,
Seventh-grade class is putting on a variety show to raise money.
The auditorium rental cost is $150.
Each ticket is priced at $5.
The goal is to raise at least $750.
Denote the number of tickets they need to sell as "x".
The revenue generated from ticket sales can be calculated by multiplying the number of tickets sold (x) by the ticket price ($5),
Which gives us 5x dollars.
Now since,
Total revenue from ticket sales - Auditorium rental cost ≥ Fundraising goal
Therefore,
5x - 150 ≥ 750
Add 150 to both sides:
5x ≥ 900
Divide both sides by 5 to solve for x:
x ≥ 180
Since the seventh-grade class cannot sell a fractional number of tickets,
Hence,
They need to sell at least 180 tickets to raise at least $750 and cover the auditorium rental cost.
