PLZZZ HELP I WILL GIVE BRAINLIEST Solve the equation
(x-3)^3-( x - 1 )^3 + 7x^2 = 7(3x - 4 )

(x - 3)³ - (x - 1)³ + 7x² = 7(3x - 4)

=> x³ - 9x² + 27x - 27 - (x³ - 3x² + 3x - 1) + 7x² - 21x + 28 = 0

<=> -2x² + 6x + 1 + 3x² - 3x + 1 = 0

<=> x² + 3x + 2 = 0

<=> (x + 1)(x + 2) = 0

<=> x + 1 = 0 or x + 2 = 0

<=> x = -1 or x = -2

283 square feet

step-by-step explanation:

good luck

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
