What is the value of x when the expression 12x + 7 equals the expression -8 + 13x? Use algebra tiles to model the equation

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

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?

What is the total area of the figure?
