Answer:
first one
Step-by-step explanation:
Yes, because 11 2/3 is rounded to 12. and 2 5/6 is rounded to 3. 12 divided by 3 is 4. 4 2/17 is rounded to 4. 4 =4
The expression is an illustration of the summation notation
The expanded form of the summation notation
is 0^4 + 1^4 + 2^4 + 3^4+4^4
<h3>How to determine the expanded form</h3>
The summation notation is given as:

The above summation notation represents the sum of the numbers raise to the power of 4, from 0 to 4
So, we have:

Hence, the expanded form of
is 0^4 + 1^4 + 2^4 + 3^4+4^4

P=2(L+W)
P=364
L=99
sub and find W
364=2(99+W)
divide both sides by 2
182=99+w
subtract 99 from both sides
83=W
w=83ft
