Hey everyone this is your boy silly I'm asking how to factorise 12x cubed - 18x​

What is the nth term rule of the linear sequence below? 27 , 25 , 23 , 21 , 19 , . .

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

Ithink i know it but i want to be sure so can you me out ?
