Answer quick
the dimensions of various-sized rectangular trays are created using the expression x – 1 for the width and x + 5 for the length. the function a(x) = x2 + 4x – 5 represents the area of the trays. the maximum length of the trays is 12 inches. the mathematical range of the function is y ≥ −9.
how does this differ from the reasonable range?
the reasonable range is 0 < y ≤ 12.
the reasonable range is 0 < y ≤ 72.
the reasonable range is 0 < y ≤ 7.
the reasonable range is 0 < y ≤ 187.

0 < y ≤ 72.

Step-by-step explanation:

We are given the maximum length of the tray is 12 inches. This implies that;

x + 5 ≤ 12

x ≤ 7

Therefore, the maximum value of x is 7 inches. The maximum width will thus be;

x - 1 = 7 - 1 = 6 inches.

The maximum area, y, will thus be;

Area = length * width

Area = 12 * 6 = 72

The reasonable domain will thus be;

0 < y ≤ 72.

The area is simply between 0 and 72. The area of any object can not be negative.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

is there any photos or whatever?
