After combining all like terms, give an expression that is equivalent to (-5a^3-2a^2)+(6a^3+9a^2+8a) Show all work.

a² + b²= c²

24² + 7² = c²

c= 25

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 k side

step-by-step explanation:

plese mark mde brainliest!

what is the rest of the question? ?
