Answer:
No, mn is not even if m and n are odd.
If m and n are odd, then mn is odd as well.
==================================================
Proof:
If m is odd, then it is in the form m = 2p+1, where p is some integer.
So if p = 0, then m = 1. If p = 1, then m = 3, and so on.
Similarly, if n is odd then n = 2q+1 for some integer q.
Multiply out m and n using the distribution rule
m*n = (2p+1)*(2q+1)
m*n = 2p(2q+1) + 1(2q+1)
m*n = 4pq+2p+2q+1
m*n = 2( 2pq+p+q) + 1
m*n = 2r + 1
note how I replaced the "2pq+p+q" portion with r. So I let r = 2pq+p+q, which is an integer.
The result 2r+1 is some other odd number as it fits the form 2*(integer)+1
Therefore, multiplying any two odd numbers will result in some other odd number.
------------------------
Examples:
- 3*5 = 15
- 7*9 = 63
- 11*15 = 165
- 9*3 = 27
So there is no way to have m*n be even if both m and n are odd.
The general rules are as follows
- odd * odd = odd
- even * odd = even
- even * even = even
The proof of the other two cases would follow a similar line of reasoning as shown above.
Answer:
Only one person is in the stopped vehicle
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
side angle side
just look at the angle with the red line in the corner and for the side look at the two marks in the same spot you know its right because you only need to flip it for them to look the same
Let hamburger = fries + 50
2hamburger + 3fries = 1700 **Given**
2(fries+50) + 3fries = 1700
2fries + 100 + 3fries = 1700
5fries = 1600
fries = 320
hamburger = 320 + 50
hamburger = 370 cal
