8-10y+12x-15xy factorise

(4 - 5y)(2 + 3x)

Step-by-step explanation:

Given

8 - 10y + 12x - 15xy ( factor the first/second and third/fourth terms )

= 2(4 - 5y) + 3x(4 - 5y) ← factor out (4 - 5y) from each term

= (4 - 5y)(2 + 3x) ← in factored form

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
