Which expression demonstrates the use of the commutative property of addition in the first step of simplifying the expression (–
1 i) (21 5i)? (–1 i) (21 5i) 0 –1 (i 21) 5i (–1 21) (i 5i) –(1 – i) (21 5i)
2 answers:
Answer:
A : (–1 + i) + (21 + 5i) + 0
Step-by-step explanation:
got it right on edge
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)
