First you have to do the problem in the perenteces, so 21 + 42 = 63. Now we have to do 63 x 3 which is 189. We have to do the second one now so 18 + 12 is 30, and now we times that by 4, so know it is 120. Lastly we add 189 + 120 which gives us an answer of 309.
It is 309.
Answer:
B C and F
Step-by-step explanation:

D and E have curves therefore they cannot be classified as polygons
A is not closed therefore it A is not a polygon
B, C and F are closed and use only straight lines therefore those 3 are polygons
Answer:
-1
Explanation:
The slope is equal to the rise/run of the line, or in other words, the number of units the line travels upwards per the number of times the line travels to the right.
We can see that for every -1 units the line travels upwards, the line travels right 1 unit. Therefore, the slope is -1/1, which is the same as -1.
I hope this helps!
