Answer:
Triangular Prism
Step-by-step explanation:
We are given the object 'Tent' and are required to find a 3D object resembling it.
Since, the object represents a tent. So, it must have two similar and parallel bases with parallelograms as sides.
Therefore, we get that the 3D object that resembles a tent is a 'Triangular Prism'.
A triangular prism has two similar triangular bases and three rectangular sides as shown in the figure below.
Hence, 'Triangular Prism' is the answer.
Solving steps:
3x - 9y = -18
divide both sides by 3
3x - 18 + 9y
therefore, x = 6+3y
We cannot solve this further, therefore x = 6 + 3y
