Bob spent $90 for 15 gallons of gas. Draw a graph, identify the unit rate, and write an equation.

**The x - axis is gallons, the y-axis is $.

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?
