D) 9x7x9x9x7x9.
What’s the index notation?

figure c

step-by-step explanation:

hope this .

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

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
