Which values of x are point(s) of discontinuity? x = –6 x = –2 x = 0 x = 2 x = 4 Which are removable discontinuities?

the answer would be 9 because if it is perpendicular to the green line. the red lines slope is the opposite or reciprocal of the slope of the green line.

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
