Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
Polygon X is similar to polygon.
And Polygon X is three times the size of polygon Y.
So, it becomes,

Hence, perimeter of polygon Y is 27.
Therefore, Option 'C' is correct.
Answer:
- All four of the remaining faces will be 4 inches wide.
Step-by-step explanation:
A right rectangular prism with square base and top with sides of 4 in.
It has four sides of 4 in wide each and of equal height of unknown measure.
<u>Options:</u>
All four of the remaining faces will have a height of 4 inches.
- Incorrect, the height is unknown.
There is not enough information to tell what the other faces will look like.
- Incorrect, all the other faces are rectangular.
Two of the remaining faces will be 4 inches wide.
- Incorrect, all the faces are 4 in wide.
All four of the remaining faces will be 4 inches wide.
A and T are points. On their own, they cannot define a line. So we can rule out choice A
WCR and TRA are angles. For any triple the points do not fall on the same straight line. So we cannot define any lines here. This crosses off choice B
Choice C is the answer because WC does define a line. We only need two points to form a line. Similarly CR does the same job. We draw a line marker with two arrows at each end to be placed over the letters to indicate "line".
Choice D is similar to choice D; however, it is not the answer because WT is the same line as WC. In other words, WC = WT. We haven't named a new line at all. We're simply repeating ourselves.
-6+ -6- -2
Adding a negative is the same as subtracting a positive.
-6 - 6 - -2
Subtracting a negative is the same as adding a positive.
-6 - 6 + 2
Subtracting a number from a negative number is like adding the positive numbers, just remember to put the negative sign in front of the number.
-12 + 2
Adding a positive number to a negative number is like subtracting a positive from another positive, but don't forget the negative sign when you're done.
-12 +2 = -10
