Answer: 7a^2+2a+7
Step-by-step explanation:Distribute the Negative Sign:
=9a2+7a+8+−1(2a2+5a+1)
=9a2+7a+8+−1(2a2)+−1(5a)+(−1)(1)
=9a2+7a+8+−2a2+−5a+−1
Combine Like Terms:
=9a2+7a+8+−2a2+−5a+−1
=(9a2+−2a2)+(7a+−5a)+(8+−1)
=7a2+2a+7
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 .
