Answer:
225
Step-by-step explanation:
If you move the bottom triangle up (as shown in the picture) it's not actually a square. And they haven't provided you with enough information to solve for anything unless there are still unknown values. You would need to know at least another leg length or angle. If they want the actual value in square millimeters, my best guess is that it's <em>supposed </em>to be a square. Since a square has sides of the same length, the area would be 15 * 15 which is 225.
In an ordered pair, x is the first number and y is the second number. So this is telling you x=1 and y=-5. You can take this information and plug it into the formulas.
x + 2y = -9
1 + 2(-5) = -9
1 + -10 = -9? True
x - y = 6
1 - -5 = 6? *
1 + 5 = 6? True.
(*Subtracting a negative makes it a positive.)

x = -5/3
Answer:
neither they are the same as each other...
Im guessing your saying how do you write 1.92 x 10 when you multiply you dont need to line up your decimals but it would lookm something like this:
1.92
x 10
and if it was 1.92 and 10.0 it would look like this
1.92
x 10.0
the deimals dont line up because you are multipling but if you were adding or subtrcating then you would have to line it up but not in this case
