Answer:
2nd row, circle is <u><em>6</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>y</em></u><em>.</em>
3rd row, rectangle is <u><em>3</em><em>x</em><em> </em><em>+</em><em> </em><em>y</em></u><em> </em>and circle is <u><em>5</em><em>x</em></u><em>.</em>
Step-by-step explanation:
As the question say when 2 rectangles, at the sides are add up together, it will form circle in the middle. So in order to find circle or rectangle, you either have to add or substract :
For 2nd row, circle,
T/L(r) + B/R(r) = M(c)
4x + 3y + 2x - y = M(c)
6x + 2y = M(c)
M(c) = 6x + 2y
For 3rd row, rectangle,
T/L(r) + B/R(r) = M(c)
x + 4y + B(r) = 4x + 5y
B(r) = 4x + 5y - x - 4y
= 3x + y
For 3rd row, circle,
T/L(r) + B/R(r) = M(c)
2x - y + 3x + y = M(c)
5x = M(c)
M(c) = 5x
* Take note, for 3rd row, you first have to find the rectangle then circle.
Symbols :
- T/L(r) = Top/Left (rectangle)
- B/R(r) = Bottom/Right (rectangle)
- M(c) = Middle (circle)
You can name Plane P, many different ways,
Assuming you are asking this out of a textbook staring at a figure of a Parallelogram, their are probably points inside that shape and the way you would name it would be naming using any three points in the plane that are NOT on the same line in any order. <span />
If it moves 423 feet in 7 minutes, you divide 423 by 7 to see how much it moves per minute, which is Around 60.4 feet per minute
Answer:

Step-by-step explanation:
Whenever we are doing unit conversions, we have to remember to make the first ratio and then each successive ratio should be put <em>in such a way</em> that the top and bottom cancels out with each unit and whatever we want, remains.
A simple example would be if we were to just convert from cm to mm. Suppose we want to convert 5 centimeters to millimeters. We can write the ratios is 2 ways:
First:

Second:

The first one is correct since we want mm, mm should be on top and cm should be on bottom form cm and cm to get canceled.
Now, for our problem, we want mm on top and day on bottom. So, cm and year should cancel. Looking at the first choice, the conversion factors are correct & skimming through, we see that
cm and cm cancels (top and bottom), also year and year cancels (top and bottom), it will leave us with mm on top and days on bottom, <em>which is what we want</em>.
First answer choice is right.
