7th grade pre algebra
We need assistance solving 3 + 2(k+1) = 6 + 3k I know the 2(k+1) has to become 2k + 2 then we have 3 + 2k + 2 = 6 + 3k then we can subtract 3k from both sides to get 3 +2k + 2 - 3K = 6 But can I combine the 3+2 on the left and the 2k - 3k to get -1k? leaving us with 5 -1k = 6...

say A -> B + 5kJ would reactants have more enthalpy or products have more enthalpy? I think first, the delta H would be negative. So H final must be less than H initial. So reactants have more enthalpy?

Is there a salt bridge in a fuel cell? I think there isn't one because hydroxide ions and hydrogen ions are in the water, so they can move around freely already.

They all have values around there, so I'm sure the proportionality is something like that. But I'm supposed to graph it to show this proportionality and I'm not sure what goes on the axis. Is the y-axis f and x-axis 1/length^0.5 or is the y-axis 1/f^2 and x-axis ...

Using the data below, suggest a proportionality statement. Length (cm) Frequency (Hz) 100 0.46 80 0.52 60 0.62 40 0.74 20 1.01 I think it's f ¡Ø 1/¡Ìlength (one over square root of length) or is it l ¡Ø 1/f^2 By the way, the length is...

Which point is a solution of the system? Y=x-9 X+2y=3

where does the "3" go then? 3x^2+3 = 3 x(x^2 + 1) = "3"(x+i)(x-i) because the answer is: (x-1)(3x-1)(x+i)(x-i)

how do you factor the polynomial 3x^4-4x^3+4x^2-4x+1? i got (x-1)(3x-1)(3x^2+3) but the answer is (x-1)(3x-1)(x+i)(x-i)
