They can just do "3*4" instead of "x*4 when x=3"
I know... I know... It's a silly question.
Answer:
Not silly, i understand but "x" is supposed to be a subsitute for a number after the many equations youll be learning in algebra. x can be anything, it isnt set to anykind of specifac number but rather an output of an equation. It is fustrating but i reccomend khan acdemy videos or math nation since they specialze in thses kinds of maths

The full height is 20, and the height of the parallelogram is 10. So that means the triangles height is 20-10=10. The top and bottom sides of a parallelogram are the same, so the base of the triangle is 18-(6+5)=7. So the area of the triangle is (7x10)/2=35. The area of a parallelogram can be count that same way as a regular rectangle. So 18x10=180. Putting those two together, 35+180=215.

Find the measure of ∠NED, not ∠CED.
Answer:
[tex] m\angle NED = 100\degree [/tex]
[tex] m\angle CED = 80\degree [/tex]
Step-by-step explanation:
By exterior angle theorem:
(9x - 8)° = (5x - 10)° + 50°
(9x - 8)° = (5x - 10 + 50)°
(9x - 8)° = (5x + 40)°
9x - 8 = 5x + 40
9x - 5x = 40 + 8
4x = 48
x = 48/4
x = 12
(9x - 8)° = (9*12 - 8)° = (108 - 8)° = 100°
[tex] \implies m\angle NED = 100\degree [/tex]
[tex] m\angle CED = 180\degree - 100\degree [/tex] (Linear pair angles)
[tex] \therefore m\angle CED = 80\degree [/tex]

Measure of Exterior Angle of a triangle is equal to the sum of measures of two opposite interior angles .
From above statement we have :
[tex] 9x - 8 = 5x - 10 + 50[/tex][tex]9x - 5 x = 40 + 8[/tex][tex]4x = 48[/tex][tex]x = \dfrac{48}{4} [/tex][tex]x = 12[/tex]_____________________________

A triangle has vertices (0, 2), (3, 1), and (6.2). What is the approximate perimeter of the triangle? Round your answer to the nearest hundredth.
Answer:
6 + 2√10 units.
Step-by-step explanation:
We can use the distance formula to find the distance between the points. The points are ,
(0,2)(3,1)(6,2)Distance 1 :-
=> D₁ = √{ (x₁ - x₂ )² + ( y₁ - y₂ )² }
=> D₁ = √{ (0-3)² + (2-1)² }
=> D₁ = √{ 3² + 1² }
=> D₁ = √{ 9+1}
=> D₁ = √10
Distance 2:-
=> D₂ = √{ (x₁ - x₂ )² + ( y₁ - y₂ )² }
=> D₂ = √{ (6-3)² + (2-1)² }
=> D₂ = √{ 3² + 1² }
=> D₂ = √{ 9 + 1}
=> D₂ = √10
Distance 3 :-
=> D₃ = √{ (x₁ - x₂ )² + ( y₁ - y₂ )² }
=> D₃ = √{ (6-0)²+(2-2)²
=> D₃ = √6²
=> D₃ = 6
→ Perimeter = D₁ +D₂ + D₃
→ Perimeter = √10 + √10 + 6
→ Perimeter = 6 + 2√10 units
Hence the perimeter is 6+2√10 units.Please answer the question correctly with factual information for brainliest.

Use technology to construct an appropriate model of the data,
(0.1). (1, 2), (2, 3), (3,-2), (4.1)
Answer:
Quadratic model
Step-by-step explanation:
Given the data :
(0.1). (1, - 2), (2, - 3), (3,-2), (4.1)
The above data point when plotted using technology gives a quadratic model with the equation : x² - 4x + 1
With the quadratic regression model for the data above, we obtain a correlation Coefficient of 1 ; which means a perfect relationship exists between the x and y variables.

If A is the center of the circle, then which statement explains how segment ED is related to segment FD?
Answer:
ED ≅ FD because segment EF is perpendicular to a radius of circle A.
Step-by-step explanation:
The statement that explains how ED is related to FD is: ED = FD because segment EF is perpendicular to a radius of circle A.
What is Does Pendicular mean?When a segment is perpedicular to the radius of a circle, it forms a right angle at the center of the segment that is intersected by the radius of the circle.
In the diagram given, based on what perpedicular mean, ED = FD because segment EF is perpendicular to one of the radii, DA, of the circle.
Therefore, the statement that explains how ED is related to FD is: ED = FD because segment EF is perpendicular to a radius of circle A.
