If the line graph has a broken line between the points, then the data has not been verified from more than one experiment the data is not actual data and is only an approximation the data is valid but is being defined for one of multiple sets of data the datahas only been verified by one other experimenter

Find the difference (8ab+a+2) - (3ab+6)

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

The square root of 9x plus 7 plus the square rot of 2x equall to 7
