Christian and Jessica‘s neighbors, Charlie and Zion also have a pool in their backyard. Charlie and Zion are always competing with their neighbors so they want to know if their pool is longer and wider than everyone else’s they know the area of their pool is represented by the equation f(x)=2x^2+5x-12 But they need to know the dimensions of their pool. Factor the function to find the dimensions of their pool what is the length and width of Charlie and Zions pool?

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
