The expression (21 + 5i) + (-1 + i) demonstrates the commutative property of addition for (-1 + i) + (21 + 5i)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Given the expression:
(-1 + i) + (21 + 5i)
Using the commutative property of addition, we get:
(21 + 5i) + (-1 + i)
The expression (21 + 5i) + (-1 + i) demonstrates the commutative property of addition for (-1 + i) + (21 + 5i)

Answer:
to find the volume of a cylinder
V=π x r^2 x h
now since we want the whole figure were going to add up the two heights to get one height number 4ft + 5ft = 9ft
V= 3.14 x 3^2ft x 9ft
V= 3.14 x 9ft^2 x 9ft
V= 254.34

We Can Let "A Number" Be M.
M Divided By 3 Less Than Itself Gives Quotient Of 8/5.
M/(M-3) = 8/5. Lets Solve.

So, What Number Can Have 3 Subtracted From It To Get Five, But Also Be Equal To Eight?
Eight Of Course!!!
So, We Know That The Number Equals 8.
Answer: 0.238853503185
(I obviously used a calculator.)
If you rounded this answer, it would be 0.24. Hope this helps!
