Step-by-step explanation:
If each side is s and the regular polygon has n sides, then the perimeter P must be n * s.
Equation for perimeter of regular polygon = ns
Given that;
Number of sides of regular polygon = n
Length of each side = s unit
Find:
Equation for perimeter of regular polygon
Computation:
Perimeter of regular polygon = [Number of sides of regular polygon[[Length of each side]
Equation for perimeter of regular polygon = [n][s]
So,

Question 5
If you add me with another number our sums will be 13, our difference is 1, find us! Who is the Smaller Number?
Blank 1:
Question 6
If you divide me by 5 and decreace that value by 2, I am 25! What's My Number?
Blank 1:
Answer:
A . The numbers are 6 and 7, with the smaller number as 6
B. The number is 135
Step-by-step explanation:
A. Let the numbers be a and b
adding both gives 13
a + b = 13 •••••(i)
difference between the two is 1
b - a = 1 ••••••(ii)
So we have two equations that we can solve simultaneously;
b = 1 + a; Substitute this into 1
a + 1 + a = 13
2a + 1 = 13
2a = 13-1
2a = 12
a = 12/2
a = 6
b = a + 1 = 6 + 1 = 7
The numbers are 6 and 7 while 6 is the smaller number
B.Let the number be x
Divide by 5; x/5, then subtract 2 , we get 25
x/5 - 2 = 25
x/5 = 25 + 2
x/5 = 27
x = 5 * 27
x = 135
Can anyone help me with this? I've been stuck on this question for some time-
Answer:
Angle E is 43 degrees.
Step-by-step explanation:
So we know that AB is parallel to CD.
We also know that Angle CHF is 119 degrees and that Angle B is 18 degrees.
First, let's find Angle DHF. It is the supplementary angle to Angle CHF. Thus, they must total 180:
[tex]\angle DHF+\angle CHF=180[/tex]
We already know that Angle CFH is 119. Substitute:
[tex]\angle DHF+119=180[/tex]
Subtract 119 from both sides:
[tex]\angle DHF=61[/tex]
Therefore, Angle DHF is 61 degrees.
Since Angle DHF is 61 degrees, then angle BGH must also be 61 degrees. This is because they are corresponding angles, and corresponding angles have the same measure.
Also, Angle BGE is the supplementary angle to Angle BGH. In other words:
[tex]\angle BGE+\angle BGH=180[/tex]
Find Angle BGE. Substitute 61 for BGH:
[tex]\angle BGE+61=180[/tex]
Subtract 61:
[tex]\angle BGE=119[/tex]
So, angle BGE is 119 degrees.
Recall that a triangle's interior angles sum to 180. This means that Angle B plus Angle BGE plus Angle E must equal 180. Thus:
[tex]\angle B+\angle BGE+\angle E=180[/tex]
Substitute 18 for B and 119 for BGE. Thus:
[tex]18+119+\angle E=180[/tex]
Add:
[tex]137+\angle E=180[/tex]
Subtract:"
[tex]\angle E=43\textdegree[/tex]
And we're done!
Remarks:
I just realized that you can just use the fact that alternate exterior angles have the same measures to figure out that BGE is equivalent to CHF. Regardless, we will arrive at the same answer :)

The coordinate of point P is
Answer:10
Step-by-step explanation:
Answer and Step-by-step explanation:
Sol: the ratio formula is
x-x1/x2-x = ratio and y-y1/ y2-y= ratio
x-(-7)/0-x=2/1 and y-17/0-y=2/1
x+7=2(-x) and y-17 = -2y
x+2x=-7 and y+2y =17
3x=-7 and 3y = 17
x=-7/3 and y= 17/3
coordinates of point p that partition the segment in ratio is (-7/3, 17/3)
The midpoint formula is:
M= (x1+x2/2, y1+y2/2)
= (-7+0/2, 17+0/2)
= (-7/2, 17/2) are the midpoint of AB.

same side exterior angles if m<1=4x+15 and m<8=3x+11, solve for the value of x
Answer:
x = 22
Step-by-step explanation:
same- side exterior angles are supplementary, thus
4x + 15 + 3x + 11 = 180, that is
7x + 26 = 180 ( subtract 26 from both sides )
7x = 154 ( divide both sides by 7 )
x = 22
4x-20=mx-5m. find m
Answer:
[tex]m=4[/tex]
Step-by-step explanation:
So we have the equation:
[tex]4x-20=mx-5m[/tex]
First, factor out a m from the right:
[tex]4x-20=m(x-5)[/tex]
Divide both sides by x-5:
[tex]m=\frac{4x-20}{x-5}[/tex]
Factor out a 4 in the numerator:
[tex]m=\frac{4(x-5)}{x-5}[/tex]
The (x-5)s cancel. Thus:
[tex]m=4[/tex]
The value of m is 4 :)

d=18+34 d=22t system of equations
Answer:{d,t}={187, 17/2}
Step by step explanation :
System of Linear Equations entered :
[1] d - 18t = 34
[2] d - 22t = 0
Graphic Representation of the Equations :
-18t + d = 34 -22t + d
Solve by Substitution :
// Solve equation [2] for the variable d
[2] d = 22t
// Plug this in for variable d in equation [1]
[1] (22t) - 18t = 34
[1] 4t = 34
// Solve equation [1] for the variable t
[1] 4t = 34
[1] t = 17/2
// By now we know this much :
d = 22t
t = 17/2
// Use the t value to solve for d
d = 22(17/2) = 187
Answer:
[tex]d=52\\t=\frac{26}{11}[/tex]
Step-by-step explanation:
1 solve for d in d =18+34
solve for d
[tex]d=18+34[/tex]
Simplify 18+34 to 52
[tex]d=52[/tex]
2 substitute d=52 into d=22t
Start with the original equation
[tex]d=22t[/tex]
Let d=52
[tex]52=22t[/tex]
3 Solve for t in 52=22t
Solve for t
[tex]52=22t[/tex]
Divide both sides by 22
[tex]\frac{52}{22} =t[/tex]
Simplify [tex]\frac{52}{22}[/tex][tex]to \frac{26}{11}[/tex]
[tex]\frac{26}{11} =t[/tex]
Switch sides
[tex]t=\frac{26}{11}[/tex]
4 Therefore
[tex]d=52\\t=\frac{26}{11}[/tex]
please help me. 5(m-7)=-8(3m+8)
Answer:
m = -1
Step-by-step explanation:
Solve for m:
5 (m - 7) = -8 (3 m + 8)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the left hand side:
5 m - 35 = -8 (3 m + 8)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the right hand side:
5 m - 35 = -24 m - 64
Hint: | Move terms with m to the left hand side.
Add 24 m to both sides:
24 m + 5 m - 35 = (24 m - 24 m) - 64
Hint: | Look for the difference of two identical terms.
24 m - 24 m = 0:
24 m + 5 m - 35 = -64
Hint: | Group like terms in 24 m + 5 m - 35.
Grouping like terms, 24 m + 5 m - 35 = (5 m + 24 m) - 35:
(5 m + 24 m) - 35 = -64
Hint: | Add like terms in 5 m + 24 m.
5 m + 24 m = 29 m:
29 m - 35 = -64
Hint: | Isolate terms with m to the left hand side.
Add 35 to both sides:
29 m + (35 - 35) = 35 - 64
Hint: | Look for the difference of two identical terms.
35 - 35 = 0:
29 m = 35 - 64
Hint: | Evaluate 35 - 64.
35 - 64 = -29:
29 m = -29
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 29 m = -29 by 29:
(29 m)/29 = (-29)/29
Hint: | Any nonzero number divided by itself is one.
29/29 = 1:
m = (-29)/29
Hint: | Reduce (-29)/29 to lowest terms. Start by finding the GCD of -29 and 29.
The gcd of -29 and 29 is 29, so (-29)/29 = (29 (-1))/(29×1) = 29/29×-1 = -1:
Answer: m = -1

how do you write a domain as an equation?
Answer: Answer
Step-by-step explanation: The domain of a function is all possible set inputs for a function. For example, if the function was {(10, 20), (10, 50), (11, 30)}, then the domains would be 10 and 11. Basically it is the first x value of each set.

The Wilson family had a family portrait framed for their living room. The frame measures 45 inches long and 37 inches wide. Which is a reasonable value for how much wall space the portrait will cover?
A. 12 ft
B. 12 ft2
C. 14 ft
D. 14 ft2
Answer:
12ft²Step-by-step explanation:
The frame is rectangular in nature, to determine a reasonable value for how much wall space the portrait will cover, we will take the area of the frame.
Given
Length of the frame = 45in
Width of the frame = 37in
Required
Area of the frame
Area of the rectangular frame = Length * Breadth
Area of the rectangular frame = 45in * 37in
Given 1feet = 12in
45in = 45/12 ft= 3.75ft
37 in = 37/12 ft = 3.083 ft
Area of the frame = 3.75ft * 3.083 ft
Area of the frame = 11.56ft²
Area of the frame ≈ 12ft²

Simplify. 4−16÷4+42 −16 13 15 16
Answer:
[See Below]
Step-by-step explanation:
✦ First split the equation in little pieces and solve them:
✧ 4 - 16 = -12
✧ 4 + 4² = 20 (4² = 16)
✦ Now divide them:
✧ -12 ÷ 20 = -0.6
So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.
