P= side+base+side
Answer:
Step-by-step explanation:
A will.
Suppose the object is placed on (5,4)
If you rotate it 180o counterclockwise, the point will become (-5,-4) (both x and y will change signs.)
Moving one unit down will still leave you in quadrant III.
If you start in another quadrant, this answer will not be correct. If the point started out in quadrant 2, rotating it 180o counterclockwise will put you in quad 4. For example
Object Start: (-2,3) Starts in quad 2
Image found: (- -2, - 3) = (2, - 3) which is in quad 4.
Answer:

Step-by-step explanation:
Answer:
10 rows with 6 passengers per row
Step-by-step explanation:
Let x be the number of rows and y the number of passengers per row.
Then we can interpret the story as the following two equations:
xy=60
(x+2)(y-1)=60
Solving these two equations:
y=60/x
(x+2)(60/x-1)=60 (substitute y)
60 - x + 120/x - 2 = 60 (multiply by -x)
x² + 2x - 120 = 0 (factor)
(x-10)(x+12) = 0
x = 10
y = 60/10 = 6
and indeed 10 * 6 = 60 and also 12 * 5 = 60
