35x + 115 = 360 35x = 360-115 35x = 245 x = 245/35 x = 7
.35x+.40*14=0.37(x+14) .35x=.37x-5.6+5.18 .35x=.37x-.42 -.02x=.42 x=21 check 21*.35+14*.4=7.35+5.6=12.95 12.95/(14+21)=.37 so you would need 21 ounces of 0.35 mixed in with 14 ounces of 40 % to get a 37% solution of which you would have 35 ounces
42x+35x-35x=42x it's leave 85 so it's change into a negative 42x-85 is the answer
x3 + 2x2 - 35x = x(x + 7)(x - 5)
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)

It is 35x.
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)
I'm guessing that's 35x^2 + 26x - 16 which factors to (5x - 2)(7x + 8)
2x + 33x - 54 35x - 54 We can not find x with the information given. You need to equate somethingto your equation. If your equation equals 0 then... 0=35x-54 35x=54 x=1.543 IF your equation equals x then... x=35x-54 -34x=-54 x=1.588
