Answer:
Step-by-step explanation:
Assuming this is the slope equation
-2 is the slope
x is point x
5 is the y intercept
y is point y
the regular equation it y = mx + b
the slope is negative so it is decreasing aka gooing down
sorryy if this is the wrong answer to your question

Answer:
a^2 +4ab+4b^2
Step-by-step explanation:
(a+2b)^2
(a+2b)(a+2b)
FOIL
first: a*a = a^2
outer: a*2b = 2ab
inner: 2b*a = 2ab
last: 2b*2b = 4b^2
Add them together
a^2 +2ab+2ab+4b^2
Combine like terms
a^2 +4ab+4b^2
Answer: 60480
Step-by-step explanation:
Given : The number of empty seats in a theater = 9
The number of customers need to find places to sit =6
Since order matters here, so we use permutations
The permutations of n things taking r at a time is given by :-
Then, the number of ways to arrange 6 seat in 9 seats :-
Hence, the number of ways to arrange 6 seat in 9 seats = 60480
