Simplify: (3x3 + 7x - 1) + (4x3 - 9x2 - 11x + 1). Write your answer in standard form. O 73 + 9x2 + 4x
0 7.23 – 9x2 - 4x
0 726 - 2x3 - 12a + 1
O 726 – 13x2

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 answer is $42.96

step-by-step explanation:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
