Answer:
Sum = -5.
Product = -2.5.
Step-by-step explanation:
For the general form ax^2 + bx + c = 0, the sum of the roots = - b/a and the product of the roots = c/a.
We have 2x^2 +10x - 5 = 0 so and the sum = -10/2 = -5 and the product = -5/2 = -2.5.

A.
Step-by-step explanation:
You don't really need much of an explanation ...
It has to do with the number of dimensions you have in the figure. For example, in a square you have 2 dimensions, length and width. Since you have only two you use units^2. In a cube, you have 3 dimensions, length, width and height, which is where you get the units^3.
