Answer:
11.3 units
Step-by-step explanation:
Let's find the length of one of the boxes.

Let's simplify c down to 1.41.
Now, there are 8 of these little boxes for the perimeter, let's multiply.

That can be simplified to the nearest tenth - 11.3
Hope this helped!
Answer:
16 rounded to the nearest 10 is 20

Answer:
21.06
Step-by-step explanation:
4.06 increased by 17
4.06 + 17
21.06
3y = 3 * 9 = 27
4z = 4 * -12 = -48
: -48 + 27 = -21
: -21 + x = 24
: X = 45.
I hope that makes sense.
