A tessellation is a tessellation that uses only one regular polygon to cover a surface completely.

Regular

Step-by-step explanation:

The answer to this question is a regular tessellation. A regular tessellation can be explained as a cover design of the plane which is done by making use of 1 type of regular polygon.

In order To make a regular tessellation, we have to make sure that the internal angle of the polygon can divide 360. This way there won't be gaps.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
