If you type the equation into y1 on your calculator and use the table graph you get coordinates that you can graph. ( 0,-9 ) ( 1,-6 ) ( 2, -3 ) ( 3 , 0 ) ( 4, 3 ) ( 5 , 6 ) ( 6 , 9 ), just graph those and that should answer your question :)
2(3x5) + 2(3x9) + 2(5x9) = 174 in2
I believe this is correct answer
Answer:
Proved below
Step-by-step explanation:
If we assume that n + 1 even when n is even, it means that;
n + 1 = 2x
Where x is an integer
Then;
n = 2x - 1
This means that n is odd because 2x - 1 is odd.
But we know that n is even, thus, our assumption is wrong.
Therefore, n + 1 is odd when n is even.
