Answer I believe that the answer is 1/36.
Step-by-step explanation: I just toke the test and got it right.
<h2><u>The value of x is equal to 6.</u></h2>
2 + 3x = 20
Subtract 2 from both sides.
3x = 18
Divide both sides by 3.
x = 6
Answer:
We need to add the expression: 
Step-by-step explanation:
As the first step, add the first two polynomials listed in order to find what their sum is. Do such by combining like terms:

now, you need to find another polynomial (let's call it P(x)) such that added to the one we just found above, will render
as a result.
Putting this phrase in mathematical terms, we write:

Now we solve for this unknown P(x) in this equation, by subtracting each of the terms that are accompanying it on the left side of the equation. We do one at a time for clarity:

Therefore, the expression we need to add is: 
Answer: 4.46 cm
Step-by-step explanation:
The image size = 30.51cm
Width of the page = 21.59cm
To know the extra width , we will subtract the width of the page from the width of the image. That is
30.51 - 21.59 = 8.92cm
to center the image , we will divide the extra width by 2 , that is
8.92/2 = 4.46cm
Therefore ; Joelle should use 4.46cm horizontal position for the left edge of the image to center the image

Answer:
x = 3
Step-by-step explanation:
You can forget about point R. It does not have any part in this problem, except to add confusion.
The given line PQ has the same y-coordinate values for points P and Q. This means the segment is a horizontal segment. Its perpendicular bisector will be a vertical line through its midpoint.
The midpoint (M) of PQ is ...
M = (P +Q)/2
M = ((-2, 2) +(8, 2))/2 = (-2+8, 2+2)/2 = (6, 4)/2
M = (3, 2)
The vertical line through a point with x-coordinate 3 will have the equation ...
x = 3
