For a display, identical cubic boxes are stacked in square layers. each layer consists of cubic boxes arranged in rows that form a square, and each layer has 1 fewer row and 1 fewer box in each remaining row than the layer directly below it. if the bottom of the layer has 81 boxes and the top of the layer has only 1 box, how many boxes are in display?
a. 236
b. 260
c. 269
d. 276
e. 285

E. 285

Step-by-step explanation:

The display forms a pyramid with each layer having a square based with one fewer row and one fewer column than the previous layer.

Since the first layer has 81 boxes, it is a 9x9 square. The next layer is an 8x8 square, followed by a 7x7 and so on.

Therefore, the total number of boxes is:

There are 285 boxes in display.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
