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:
9 loaves
Step-by-step explanation:
Judy get 3/4 of the bread, so ...
(3/4) · 12 loaves = 9 loaves
The distance traveled by Davis family = 35 miles
Time taken to cover the distance = 
hour
Speed = Distance 
Time
Speed = 
Speed = 
So, speed = 70 miles/hour.
At 2:00 pm, the family destination was 245 miles away.
So, the number of hours, when the family was 245 miles away = 
= 3.5 hours
So, after 3.5 hours, that is at 5:30 pm, the Davis family will be 245 miles away.
The highest common factor of the two terms is 3, so that goes outside the bracket as 3(____). To get 3x^2, you multiply 3 by x^2, which is your first term in the bracket, and to get -21, you multiply 3 by -7, so your final answer is 3(x^2 - 7). I hope this helps!
