How many lines of symmetry does the following figure have?
In an equilateral triangle, the number of line of symmetry is three. Then the correct option is C.
What is the axes of symmetry?If a line intersect the shape and the shape look identical on both sides of line, then the line is known as axis of symmetry.
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
If all the sides of the triangle are congruent, then the triangle is known as an equilateral triangle.
And each angle of the equilateral triangle is 60 degrees.
In an equilateral triangle, the number of line of symmetry is three.
And each axis of symmetry bisects the side of the triangle.
Then the correct option is C.

Marcello is tiling his kitchen floor with 45 square tiles. The tiles come in whole number side lengths of 6 to 12
inches. The function A(s) = 45s2
, where s is the side length of the tile, represents the area that Marcello can cover
with the tiles. What is the domain of this function?
Answer:
Domain: {6, 7, 8, 9, 10, 11, 12}
Step-by-step explanation:
Domain is the set of input values.
Now, we are told that s is the side length of the tile, represents the area that Marcello can cover and that the tiles come in whole number side lengths of 6 to 12.
Thus, the possible sizes are;
(6, 7, 8, 9, 10, 11, 12)
This will also be the domain

What number is one hundred less than 921
Answer:
821
Step-by-step explanation:
921 - 100 = 821
The number which is one hundred less than 921 is 821.
We have the following statement - what number is one hundred less than 921.
We have to identify the number.
If a number 'x' is 50 less than 'y', then find x.The number x can be given by the following equation -
x = 50 - y
According to the question, we have - a number which is one hundred less than 921.
Assume the number to be x. Then -
x = 921 - 100
x = 821
Hence, the number which is one hundred less than 921 is 821.

Find f(-10)
NEED IT FAST
Answer:
[tex]f(-10)=186[/tex]
Step-by-step explanation:
We can use substitution to find the value of [tex]f(-10)[/tex].
[tex]f(x) = 2x^2+x-4[/tex]
[tex]f(-10) = 2(-10)^2-10-4[/tex]
[tex]=200-10-4[/tex]
[tex]=186[/tex]
∴ [tex]f(-10) =186[/tex]
Hope this helps :)
Answer:
The value of f(-10) is equal to 186.
Step-by-step explanation:
We are given the function:
[tex]f(x) = 2x^2 + x - 4[/tex]
We are told to find the value of:
[tex]f(-10)[/tex]
If we pay close attention, we can see a transition between:
[tex]f(x) \rightarrow f(-10)[/tex]
We have turned x into -10, making x = -10.
Therefore, we can change the value of x in the entire function to -10.
[tex]f(-10)=2(-10)^2+(-10) - 4\\\\f(-10) = 200 - 10 - 4\\\\f(-10) = 186[/tex]
Therefore, f(-10) = 186.

21. Find x, given AD = BC =6 m.
Answer:
Draw a perpendicular line from point A to line segment BC. Name the intersection of said line at BC “E.” You now have a right angled triangle AED.
Now, you know AD = 6 m. Next, given that the trapezoid is a normal one, you know that the midpoints of AB and DC coincide. Therefore, you can find the length of DE like so, DE = (20–14)/2 = 3 m.
Next, we will use the cosign trigonometric function. We know, cos() = adjacent / hypotenuse. Hence, cosx = 3/6 = 1/2. Looking it up on a trigonometric table we know, cos(60 degrees) = 1/2. Therefore, x = 60 degrees.
Alternatively, you could simply use the Theorem for normal trapezoids that states that the base angles will be 60 degrees. Hope this helps!

Pls I need help !!!!!
Answer:
a=8
Step-by-step explanation:
We know that the right triangle has a total angle of 90.
We already have 50 witch means 40 is missing.
The equation given is:
6a-8 but we will upgrade it by the information we have so now it’s 6a-8=40
One of the multiples of 6 is, 6x8=48
Remember that 8 will be taken off.
Solve:
48-8=40 (witch is what we where looking for)
This is further proof that a=8
I have no idea what the answer is
