What is the seventh term in the geometric sequence a3=125 and r=5?

30 determine the coefficient on x 12 y 24 x12y24 in ( x 3 + 2 x y 2 + y + 3 ) 18 . (x3+2xy2+y+3)18. (be careful, as x x and y y now appear in multiple terms! )

What’s 8y+48 and factor each expression completely

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
