Answer:
4√5 + 4√10
Step-by-step explanation:
The perimeter is the sum of all the sides.
Using the coordinates given to us, we can find the sides of the quadrilateral.
d(ab) = √[(x2 - x1)² + (y2 - y1)²]
Given that, we apply that to each and every of the side, and thus we have
d(le) = √[(3 --3)² + (3 - 1)²]
d(le) = √[(6²) + (2)²]
d(le) = √(36 + 4)
d(le) = √40
d(ea) = √[(5 - 3)² + (7 - 3)²]
d(ea) = √[(2)² + (4²)]
d(ea) = √(4 + 16)
d(ea) = √20
d(ap) = √[(-1 - 5)² + (5 - 7)²]
d(ap) = √[-6)² + (-2)²]
d(ap) = √(36 + 4)
d(ap) = √40
d(pl) = √[(-1 --3)² + (5 - 1)²]
d(pl) = √[(-2)² + (4)²]
d(pl) = √(4 + 16)
d(pl) = √20
Perimeter of the quadrilateral is then
d(le) + d(ea) + d(ap) + d(pl)
√40 + √20 + √40 + √20
4√5 + 4√10

Hi!! I'd love to help!!
The slope of your points is 2.
When we use the slope intercept formula (y=mx+b), we get y=2x-2.
So the answer to your question is C
Hope this helps!! Let me know if you need any more help or have questions/concerns.
HELP, i’m struggling
Answer:
x = 14
Step-by-step explanation:
(3x + 8) = (4x - 6)
3x + 8 = 4x - 6
+6 +6
3x + 14 = 4x
-3x -3x
14 = 1x
x = 14
plug 14 into the x, then solve it urself

Lanu draws a rectangle that is 10 inches wide and 20 inches
long. Which rectangle described below has the same area?
F 5 inches wide and 25 inches long
G 8 inches wide and 25 inches long
H 15 inches wide and 15 inches long
J 15 inches wide and 25 inches long
Answer:
G
Step-by-step explanation:
A 10 x 20 inch rectangle has an area of 200 square inches. Therefore, we must find the rectangle that is also 200 square inches.
The formula of finding the area of a rectangle is multiplying width times length.
F) 5 * 25 = 125
G) 8 * 25 = 200
H) 15 * 15 = 225
J) 15 * 25 = 375
Therefore, rectangle G has the same area, since it is also 200 square inches.

You have $75 and need to buy 9 books at the bookstore and each book costs d dollars.
Write an algebraic expression to represent the amount of money left over.
Answer:
75-9d
Step-by-step explanation:
Hello,
The Answer to the question is 75-9d let me explain why,
you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.
You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.
75 - 9d
75 is the total. You need to subtract it by how many books your buying, 9.
The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs
Hope you can understand, I was having some trouble finding a way to explain it so my bad.
Also, I haven't done that in a while so sorry if I'm wrong

How do you find the height of a parallelogram without the area of it?
Answer:
See: https://brainly.in/question/12682555
Step-by-step explanation:
The link provided will take you to a differently worded explanation from another user.
You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:
c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
The manager of a company wants to find out how many hours the employees worked in the previous month. Which of the following is a statistical question that the manager can ask? A. How many employees are there in the company? B. Which employee worked the most hours in the last month? C. How many employees worked more than 35 hours this week? D. How many hours does each employee work in a week?
Answer:
B. How many hours does each employee work in a week?
Step-by-step explanation:
A statistical question is one that has a variable answer.
The answers to the question, "How many hours does each employee work in a week?" vary by employee, so it is a statistical question.

Answer:
32
63
Step-by-step explanation:
m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.
m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.
Step-by-step explanation:
148 + x = 180
x = 180 - 148
x = 32
Find m<CAB basically means find the measure of the angle of A ( m<A )
m<B + m<A + x = 180
85 + m<A + 32 = 180
117 + m<A = 180
m<A = 180 - 117
m< A = 63, so m<CAB = 63
And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.
So m<BCA = 32

What is the area of this polygon?
Answer:
45
Step-by-step explanation:
The area can be found by sectioning the polygon into three shapes. A rectangle with an area of 18 inches can be found at the bottom, while the top can be divided into two triangles. The triangle on the left has an area of 18in^2, (1/2*6*6) while the triangle on the right has an area of 9 in^2 (1/2*6*3).
Total area for all three shapes is 45 sq. inches

In a school, 4 out of every 7 students are girls. if there are 84 students at the school, how many are boys. AND SHOW WORKING
Answer:36
Step-by-step explanation:
[tex]\frac{4}{7} =\frac{48\\}{84}[/tex]
for every 7 students there are 4 girls, so for every 84 there must be 48
7*12=84
4*12=48
so, in all 84 students there are 48 girls
so amount of boys=84-48=36
there are 36 boys

Here is a list of numbers.
32 29 30 37 34 33 31
Tanya thinks that to work out the median, she simply needs to find
the middle number. So she says that “37" is the median for this list of numbers.
Tanya's answer is not correct.
a) Describe what is wrong with her method.
b) Work out the median of the numbers in the list.
Answer:
a). To find the median from a set of numbers, you need to arrange them from ascending order (smallest to biggest), and then you need to find the number in the middle
b). 32
Step-by-step explanation:
b). Smallest to biggest
29, 30, 31, 32, 33, 34, 37
From the set of numbers given, we can clearly see that 32 is in the middle.

Find the perimeter of an isosceles triangle whose base is 16 cm and whose height is 15 cm.
Answer:
50 cm
Step-by-step explanation:
The altitude from the vertex to the base bisects the base and divides the triangle into 2 right triangles.
Using one of the right triangles with legs 8 and 15 , then hypotenuse h is
h² = 8² + 15² = 64 + 225 = 289 ( take the square root of both sides )
h = [tex]\sqrt{289}[/tex] = 17
The 2 congruent sides of the isosceles triangle are 17 cm
Then the perimeter P is
P = 17 + 17 + 16 = 50 cm

to do that like the first 1 u do 2 x ? = 100 the answer is 50
Rule what u do to the bottom u have to do to the top
now that u multiply 50 down to make 100 u have to do as the rule say what u need to do is also multiply 1 to 50 to get the answer
as u might know that 100 mean % so u pet the top number and then %
