Factor the polynomial completely using the X method. x2 + 16x + 48 An x-method chart shows the product a c at the top of x and b at the bottom of x. Above the chart is the expression x squared + 16 x + 48. Which equivalent four-term polynomial can be created using the X method? x2 + 8x + 8x + 48 x2 – 12x – 4x + 48 x2 + 12x + 4x + 48 x2 – 8x – 8x + 48

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
