What is the perimeter of this shape?
2 answers:
Answer:
87 feet
Step-by-step explanation:
Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:
30+9+12+9+9+9+9=87 feet
Hope this helps!

No they cannot because if the planes intersect they will crash
Answer:
B
Step-by-step explanation:
Answer:
52 and 38
Step-by-step explanation:
If x = 13 then 4x = 4 * 13 so 52.
Same for the next one. 2x = 2 * 13 so 26. 26+12 is 38.
Done...
Use Pythagoras's theorem.
Now, minus 12 from 15:
15 - 12 = 3,
which you need to square.
So the length of a = 9cm.
You can also do:
Which gets 9.
