False

Step-by-step explanation:

A regular sided polygon means all the sides have the same length and all angles the same size.  This polygon has 2 sides the same length, not 3 sides the same length, so it cannot be regular.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

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
