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)

(sorry if it's wrong)
The r variable outside the parentheses can multiply both the numbers in the parentheses.
This called distributing the r. We are using the distributive property.
The distributive property states that a(b + c) = ab + ac.
r(18 - 3) = 18r - 3r
So, (r * 18) - (r * 3) is the answer.
In this, we have to see if we can get a common ratio between both of the triangles. Lets start by dividing 5 from 10. From this, we get 2. If we divide 7 from 14, we also get 2, so we know that they are similar. Therefore, both of them are similar because AB/FD = AC/FE
