Answer:
Infinite solutions
Step-by-step explanation:
All solutions are possible.
Hello, hope you are having a wonderful day.
A point has 0 dimensions. It has no length, width, or depth.
So any point in space has 0 dimensions.
Now, a line has 1 dimension.
Rectangles, squares and other shapes have 2 dimensions.
Cylinders, cubes, cones and other figures have 3 dimensions.
Hope it helps. Please mark Brainliest; I really need it.

Good luck.
Answer:
A has to be 2
Step-by-step explanation:
In the expression 
, the multiplicative factor A represents what is called the "amplitude of the wave-shaped function that you obtain as the graph. Such amplitude is understood as half of the crest-to-through distance of the wavy curve.
From the drawing, the crest is at y=2 and the through at y=-2 (a distance of 4 units) therefore the value of A should be half of that distance: 4/2 = 2
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- x²+y²<span>=74
xy=35
2. Therefore, you have that (x-y)</span>² is:
=(x-y)²
=x²-2xy+y²
=(x²+y²)-2xy
3. When you substitute the values given in the problem, you obtain:
=74-2(35)
=74-70
=4
4. Therefore, as you can see, the correct answer is: 4
