Step-by-step explanation:
The distance between two point (x_1, y_1) and (x_2, y_2) is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Therefore, the distance between (-1,4) and (1,-1) is
[tex]d=\sqrt{(1-(-1))^2+(-1-4)^2}=\sqrt{4+25}=\sqrt{29}=5.4[/tex]
The average of five numbers is 34. Two of the numbers are the same, and the other three are 49, 25, and 42. Find the value of the two numbers missing numbers.
Answer:
Both numbers = 27
Step-by-step explanation:
( x + x + 49 + 25 + 42)/ 5 = 34 Multiply both sides by 5
(2x + 49 + 25 + 42) = 34*5 = 170 Combine the left
(2x + 116) = 170 Remove the brackets.
2x + 116 = 170 Subtract 116 from both sides
2x = 170 - 116
2x = 54 Divide by 2
x = 54/2
x = 27
Check
27 + 27 + 49 + 25 + 42
170 / 5 = 34
It does check out.
27 is right.
What are the equations?
1. Two more than the product of 3 and a number is -10. Determine the number.
2. The sum of three times a number and 20 is 11. Determine the number.
3. Seven-tenths of a number is 5.6 Determine the number.
Step-by-step explanation:
1. Let the number be a
2 + 3a = (-10)
3a = -10 - 2
3a = -12
a = -12/3 = -4.
2. Let the number be x
3x + 20 = 11
3a = 11 - 20
3a = -9
a = -9/3 = -3
3. Let the number be n
7x/10 = 5.6
x = 5.6 × 10/7
x = 56/7
x = 8

What is the like terms on this equation
3+5–2x–54-7
Answer:
3, 5, -54, and -7 are like terms while -2x stays alone.
Step-by-step explanation:
3+5-2x-54-7=0
3+5-2x-61=0
5-2x=61-3
5-2x=59
-2x=59-5
-2x=54
(-x)=54/2
(-x)=27
x=-27

f (8^9)p = 8^18, what is the value of p? (5 points)
A 2
B 9
C 10
D 18
Answer:
A
Step-by-step explanation:
I'm assuming p is an exponent.
You can multiply the exponent p with 9
8^9p = 8^18
Now we know that some number times the exponent 9 gives us 18.
Now, we isolate for p, by putting 9 on the other side, we know we can do this because both number have the same base (8)
therefore, 9p=18
p=18/9
p=2

List three different properties of a square
Answer:
All four sides of a square are equal in length, all interior angles of a square are right angles, all sides are parallel to an opposite side
Step-by-step explanation:
These are just 3 simple properties of many properties of a square. Obviously, a square is a quidrilateral that has four equal sides. Therefore, it makes all interior angles of the shape the same. And it is also a parallelogra, meaning that opposite sides are parralell to one another.

samar wrote a list of three square numbers. which of the following could be on samars list?
A. 4, 6, 8
B. 4, 7, 10
C. 4, 8, 12
D. 4, 9, 16
Option A "4, 6, 8".
This is because when we multiply 2x2, we get 4, then we add +2 with 4, we get 6, then we add again +2 with 6, we get 8. So, a list of three square numbers is completed.
Therefore, Option A is the correct answer.
Thank You...

1. ABCD is a quadrilateral in which AD = BC and ∠DAB = ∠CBA. Prove that δABD ≌ ΔBAC.
Step-by-step explanation:
ABCD is a quadrilateral triangle,where AD=BC and <DAB =<CBA.
In ∆ABD and ∆BAC
•AD=BC. (given)
•<DAB=<CBA (given)
•AB=BA. (common side)
Therefore, ∆ABD ≌ ΔBAC. {SAS congruence rule}
