Surface area of 10 cubes stacked

five

Step-by-step explanation:

you have to divide

42a²

Step-by-step explanation:

Let the edge be a. Ten cubes stacked means 4 vertical edges of the cubes are 10a each. The four sides have the total area of 4 x 10a x a = 40a²

The base and top of the cube are square, so the area of the base and top each is a².

The total surface area of 10 cubes stacked = 40a² + a² (base) + a² (top) = 42a²

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
