Kenny is planning to plant a rectangular garden that is 10 feet longer than it wide. kenny wants to find its width if its area is 200 square feet. write an equation that models this problem?

Which quadratic function best fits this data? x y 1 32 2 78 3 178 4 326 5 390 6 337 a. y=11.41x2+154.42x−143.9 b. y=−11.41x2+154.42x−143.9 c. y=11.41x2+154.42x+143.9 d. y=−11.41x2+154.42x+143.9

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)

Could somebody me with this radical simplification?
