Michael's little brother plays with building blocks that are in the shape of a cube. each cube has an edge length of 15 millimeters. what is the surface area of this cube? 15 mm² 90 mm² 1350 mm² 3375 mm²

1350 mm²

Step-by-step explanation:

The area of each square face is the square of the edge length:

... face area = (15 mm)² = 225 mm²

There are 6 square faces on a cube, to the total surface area is 6 times that of one face:

... cube area = 6 × face area = 6×225 mm² = 1350 mm²

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
