Step-by-step explanation:
6m+7n+5m-3n
First you rearrange the terms
6m+5m+7n-3n
Then you combine like terms
11m+4n
And there you have it
Hope it helps!
Answer:x
Step-by-step explanation:
The distance formula is: d = sqrt( (x2 - x1)2 + (y2 - y1)2 )
For this problem, let (-5, -4) be the "first" point, so x1 = -5 and y2 = -4
and let (-6, 4) be the "second" point, so x2 = -6 and y2 = 4.
Then: d = sqrt( (-6 - -5)2 + (4 - -4)2 ) = sqrt( (-1)2 + (8)2 ) = sqrt( 1 + 64 ) = sqrt( 65)
The distance formula is just the Pythagorean Theorem applied to an x-y graph.
You would get the same final answer if you let (-5, -4) be the second point and (-6, 4) be the first point.
Answer:
Lori would have to save $5,760
Step-by-step explanation:
Since 320×6=1920, you would have to add to see witch number would be best to save up too. You would get $5,760 when you multiple by 3.If you multiple by 2,it wouldn't give you enough money.
