Answer:
Commutative Property
Step-by-step explanation:
Commutative property, changes the order of the addends does not change the sum
Ex)

Answer:
2160
Step-by-step explanation:
Given : At a computer store, a customer is considering 10 different computers, 6 different monitors, 9 different printers and 4 different scanners. We assume that each of the components is compatible with one another and that one of each is to be selected. then by Fundamental counting principle , the number of different computer systems possible is given by :-
10x6x9x4= 2160
Hence, the number of different computer systems possible= 2160The Fundamental Counting Principle is a technique in Mathematics to calculate the number of possible outcomes by multiplying the events together .

Answer:
X^2+3x
Step-by-step explanation:
in order to get these roots, we would set up the equation to be (x)(x+3). We can then multiply it to get x^2+3x
