9-16. regions of integration sketch each region and write an iterated integral of a continuous function f over the region. use the order dy dx (x, y): 0 s x s /4, sin x s y s cos x

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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
