Which is the net of this solid? A pentagonal pyramid is shown. A net is shown with a square in the middle and 4 identical triangles on the 4 sides of the square. A net is shown with a pentagon in the middle and 5 identical triangles on the 5 sides of the pentagon. A net is shown with a triangle in the middle and 3 identical triangles on the 3 sides of the triangle in the middle. A net is shown with a hexagon in the middle and 6 identical triangles on the 6 sides of the hexagon.

Choice B

A net is shown with a pentagon in the middle and 5 identical triangles on the 5 sides of the pentagon

The pentagon forms the base of the pentagonal pyramid. Each lateral side is a triangle that meets at the very top of the pyramid. The base stays on the floor while the sides are folded up.

There are other possible net configurations to form a pentagonal pyramid, but the other answer choices do not make a pentagonal pyramid.

So we can rule choices A, C and D out.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
