Explanation:
For a circle with radius r, we have these formulas
area = pi*r^2 circumference = 2*pi*rEquate the two expressions and isolate r
pi*r^2 = 2*pi*r
pi*r^2 - 2*pi*r = 0
pi*r(r - 2) = 0
pi*r = 0 or r - 2 = 0
r = 0 or r = 2
A radius of 0 doesn't make much sense, so we ignore it. The only possible answer is r = 2.
-------
If the radius is 2, then,
area = pi*r^2 = pi*2^2 = pi*4 = 4picircumference = 2*pi*r = 2*pi*2 = 2*2*pi = 4piBoth result in 4pi to help confirm our answer.

Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer:
x = 5 is the answer

Solve for x.
x + 2.6 = 1.7
Answer:
x = -0.9
Step-by-step explanation:
We must isolate the x variable. We can do this by subtracting 2.6 from both sides.
x + 2.6 - 2.6 = 1.7 - 2.6
x + 0 = -0.9
x = -0.9

Answer:
the answer is 3(2+y)
Step-by-step explanation:
i commented that first it would not let me answer

Answer:
3(2+y)
Step-by-step explanation:
Sum is addition, and you need to multiply 3 by 2 and 3 by y. It has to be a because it is the only one that does 3(2+y)
B isn’t multiplying it by y
C doesn’t multiply 3 by 2
D doesn’t multiply 3 by y

Step-by-step explanation:
Translate ABC using the coordinate rule (x,y) -> (x-2, y+4)
The coordinates of all the vertices:
A = (-7,5)
B = (-5,8)
C = (-2,4)
The coordinates of ABC after using coordinate rule is;
A = (-7, 5)
B = (-2, 5)
C = (-5, 8)
And, The graph is shown in figure.
Given that;
The coordinate rule (x, y) -> (x - 2, y + 4)
We have to determine the translate of ABC by using the given coordinate rule.
What is Translation?
A translation is type of transformation that takes each point in figure and slides it the same distance in the same direction.
The points are given as;
A = (-5, 1)
B = (0, 1)
C = (-3, 4)
Since, The coordinate rule is (x, y) -> (x - 2, y + 4).
Hence, The coordinates of ABC are find as,
A = (-5, 1)
After using coordinate rule;
A = (-5-2, 1+4) = (-7, 5)
And, B = (0, 1)
After using coordinate rule;
B = (0-2, 1+4) = (-2, 5)
And, C = (-3, 4)
After using coordinate rule;
C = (-3-2, 4+4) = (-5, 8)
Now, Draw the coordinates of ABC after applying the coordinate rule.
The picture is shown the translate of ABD after using the coordinate rule.
So, The coordinates of ABC after using coordinate rule is;
A = (-7, 5)
B = (-2, 5)
C = (-5, 8)
And, The graph is shown in figure.

What is the measure of x? Answer is in decimal
Answer:
x=27.3333333°
Step-by-step explanation:
∠AOB and ∠BOC make a right angle of 90°.
x+8+2x=90
3x+8=90
3x=82
x=27.3333333
Answer:
27.34
Step-by-step explanation:
x + 8 + 2x = 90
x + 2x = 90-8
3x = 82
x = 82/3
x = 27.33333333333333333333

Step-by-step explanation:
it wants you to reorganize things by like terms
So the first blank should be your other t value
so 5/7t
The second blank would be your number with no x
so 18
and your last two blanks are the simplification
so 6/7

What is the value of x?
Answer:
x = 15
Step-by-step explanation:
Vertical angles always equal to each other so you have to do
(2x + 15) = (x + 30)
Subtract 15 from each side
2x = x + 15
Subtract x on both sides
x = 15
So your answer is x = 15
