What is the surface area of a cube that is 4 cm on each edge?

96 units squared

Step-by-step explanation:

The surface area of a cube can be written as 6 * (s^2)

s is the side length.

4^2 = 16.

6 * 16 = 96.

This is because the area of a cube is s^2.

There are 6 sides to a cube, so we multiply them.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
