what is the relationship between the number of sides in a polygon and the sum of the measures of the interior angles ?
The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.
Answer:
18x - 36
Step-by-step explanation:
In an equilateral triangle the 3 sides are congruent, then
perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms
= 18x - 36
The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
As we know in an equilateral triangle the 3 sides are congruent.
The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12
Combine the likewise terms and we get
The perimeter of the triangle = 18x - 36
Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

what is the period of the sinusoidal function
Answer:
10Step-by-step explanation:
Period is the distance between two consecutive maximum points, or two consecutive minimum points.On the given graph the period is the distance between maximum points -7 and 3:
3 - (-7) = 10Answer:
The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.
From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units
Therefore, 10 units is the right answer.

what is an equation of the line that passes through the points 0,-1 and 6,1
put answer in fully reduced form
Answer: x - x1/ x2- x1 = y -y1 / y2-y1
x - 6/ -6-6= y - 1/ -1 -1
x -6/-12 = y -1 /-2
-2(x-6) = -12 (y-1)
-2x +12 = -12y +12
12y = 2x +12-12
y= 2x/12
y= x/6
Step-by-step explanation:
Answer:
y=1/3x-1

Find the common difference of the arithmetic
sequence 13,9,5,
Answer: -4
Step-by-step explanation:
13 - 9 = 4
9 - 5 = 4
so, we can see that it is decreasing by 4 each time.
Answer:
common difference is -4
Step-by-step explanation:
The common difference is the amount we add between terms
13 + d = 9
Subtract 13 from each side
13+d-13 = 9-13
d = -4
Check
9+d = 5
9 + -4 = 5
5= 5
This is true so the common difference is -4

Which expression represents (−21−−−−√5)6 in rational exponent form? (−21)6/5 −215/6 (65)−21 (56)−21
Answer:
[tex](-21)^\frac{6}{5}[/tex]
Step-by-step explanation:
Which expression represents [⁵√(−21)]⁶ in rational exponent form?
Solution:
Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.
A rational exponent is an exponent that is a fraction. For example √2 = [tex]2^\frac{1}{2}[/tex].
When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.
[tex][\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}[/tex]

Step-by-step explanation:
(6x - 3) - (-3x + 2)
Answer:
Step-by-step explanation:
Simplifying
6x + -3 = (3x + -2)
Reorder the terms:
-3 + 6x = (3x + -2)
Reorder the terms:
-3 + 6x = (-2 + 3x)
Remove parenthesis around (-2 + 3x)
-3 + 6x = -2 + 3x
Solving
-3 + 6x = -2 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = -2 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = -2 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = -2 + 0
-3 + 3x = -2
Add '3' to each side of the equation.
-3 + 3 + 3x = -2 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = -2 + 3
3x = -2 + 3
Combine like terms: -2 + 3 = 1
3x = 1
Divide each side by '3'.
x = 0.3333333333
Simplifying
x = 0.3333333333
