Which function has a vertex at (2, -9)? 6 Of
Of(x) = -(x-3)2
f(x) = (x + 8)2
f(x) = (x - 5)(x + 1)
f(x) = -(x - 1)(x - 5)

false

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

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
