v=-1

Step-by-step explanation:

-3=-5-2v

-3+5=-2v

2=-2v

2/-2=-2v/-2

v=-1

v=−1

Step-by-step explanation:

Let's solve your equation step-by-step.

−3=−5−2v

Step 1: Simplify both sides of the equation.

−3=−5−2v

−3=−5+−2v

−3=−2v−5

Step 2: Flip the equation.

−2v−5=−3

Step 3: Add 5 to both sides.

−2v−5+5=−3+5

−2v=2

Step 4: Divide both sides by -2.

−2v

−2

=

2

−2

v=−1

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

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
