A regular pentagon and rectangle have the same perimeter. The length of the rectangle and the side of the pentagon are equal. The width is 10 more than the length. Write an equation that describes the scenario. pentagon's perimeter: rectangle's perimeter: scenario's equation:
Answer:
Pentagon perimeter 5l
Rectangle perimeter 2l +2(l + 10
Scenario’s equation 5l=2l +2(l + 10)
Step-by-step explanation:trust me
The equation that describes the pentagon perimeter is 5l
Where l is the sides of the pentagon.
The equation that describes the rectangular perimeter is 4l + 20
Where l is the length of the rectangle
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Regular pentagon:
A regular pentagon has 5 sides.
Side = l
Rectangle:
Length = l
Width = 10 + l
Now,
The perimeter of a pentagon = 5 side
The perimeter of a rectangle = 2 (l + w)
The perimeter of the pentagon.
= l + l + l + l + l
= 5l
The perimeter of the rectangle.
= 2 (l + w)
= 2 (l + 10 + l)
= 2 (2l + 10)
= 4l + 20
Thus,
The equation that describes the pentagon perimeter is 5l
Where l is the sides of the pentagon.
The equation that describes the rectangular perimeter is 4l + 20
Where l is the length of the rectangle

HELP! will mark branniest answer if right!
Answer:
64 i think
Simple explanation:
find the missing angle of the triangle with two given angles:
add 36 and 84 to get 120
subtract 120 from 180 and you will get 60
subtract 60 from 90 to find one of the angles in the other triangle
so now you have that the other triangle has an angle of 86 and another angle of 30
add 86 and 30 to get 116
subtract 116 from 180 to get the "? angle"
you should get 64
Another possible explanation:
extend the line that contains the degrees 36 and 84
this will make a third, smaller triangle
this triangle has two measure that are easy to find and that is 96 and 54
when you add those together, you get 150
subtract 150 from 180 to get 30
30 degrees is the measure of the smaller angle at the 90 degrees symbol
now add 30 and 86 together to get 116
subtract that from 180 to get 64

! pls help, I’ll mark as brainliest !
Answer:
X=-1
Y=-9
Step-by-step explanation:
x^2+2x-8
x^2+2x +1 =8+1
(x+1)-9
x coordinate of vertex x=-1, y coordinate of vertex y=-9 and x=2 and x=-4 are the x intercepts.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given equation is y=x²+2x-8
then the x-coordinate of the vertex can be found using
x=-b/2a
x=-2/2=-1
x=-1 is the x coordinate of vertex.
substitute this value into f(x) for y coordinate
y=(-1)²+2(-1)-8
y=1-2-8=-9
y coordinate of vertex y=-9.
y intercept is -8.
To find the x intercepts x²+2x-8=0
x²+4x-2x-8=0
x(x+4)-2(x+4)=0
(x-2)(x+4)=0
x=2 and x=-4 are the x intercepts.
Hence, x coordinate of vertex x=-1, y coordinate of vertex y=-9 and x=2 and x=-4 are the x intercepts.

Can someone pls answer these questions for me I’m stuck
Answer:
a) The triangles are similar, and the ratio of the similar sides are both equal to 1:3. b) the scale factor from triangle abc to def is 3 because if you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm. Using the scale factor, you can just multiply 3 by 2.5.
Step-by-step explanation:
a) If you look at the two triangles, you can see that they look similar. Side AB looks similar to side DE, and the side lengths are 1 and 3. Therefore, the scale will be 1:3. b) If you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm because the scale factor is 3, which means you have to multiply the smaller side by 3.

Find the measure of the exterior angle.
Answer:
1) 128°
2) 126°
3) 108°
Question one:The square in the corner means 90°. If you add the interior angles of any triangle together, you get 180. in this case, x is in exterior angle, so you subtract it from 180 to get the interior angle.
38 + 90 + (180-x) = 180
38 + 90 + 180 - x = 180
38 + 90 + 180 - 180 - x = 0
38 + 90 + 180 - 180 = x
128 = x
Question two:
again, adding all the interior angles makes 180°. use this to make the equation.
3x + (5x-6) + 90 = 180
3x + 5x - 6 = 90
8x = 96
x = 12.
x isn't the answer the question wants, however. if you look at the drawing, the angle that's supplementary to 5x-6 is the exterior angle. so,
180 - (5x-6) = the answer
180 - 5x + 6 = the answer
substitute x for 12
180 - 60 + 6 = the answer
126 = x
Question three
again, adding all the interior angles together makes 180°.
(a + 10) + 44 + (180-2a) = 180
a + 10 + 44 + 180 - 2a = 180
-a + 234 = 180
234 - 180 = a
54 = a
however, the question is looking for the exterior angle, not a. in this case, the exterior angle is 2a, so just multiply 54 by 2.
x = 108

Cypress Middle School wants to have a fundraiser to buy art supplies. Fundraiser A will give the school $1.50 for each order places plus $75 as a bonus. Fundraiser B will give the school $3.00 for each order placed, but no bonus. How many orders must be placed in order for the total amount of money earned by each fundraiser to be the same?
150
Answer:
The indifference point is 50 orders.
Step-by-step explanation:
Giving the following information:
Fundraiser A:
$1.50 for each order places plus $75 as a bonus.
Fundraiser B:
$3.00 for each order placed.
First, we need to structure the fundraisers' formula:
Fundraiser A= 75 + 1.5x
Fundraiser B= 3x
x= number of orders
Now, we equal both formulas and isolate x:
75 + 1.5x = 3x
75/1.5= x
50= x
The indifference point is 50 orders.
Prove:
Fundraiser A= 75 + 1.5*50= $150
Fundraiser B= 3*50= $150
