What is (2x)(x). you are multiplying 2x by x.

This would be an example of verbal use to make this easier on yourself put x to the second power then multiply by 2 so //2*x(to the second power) = 2*to the second power

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

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
