The GCF is 2z
Since 2z^2 is a factor fo 4z^3, it is automatically the GCF.
4z squared (z+4) (z+4)
-8z + 12 = 12 - 4z-8z +4z + 12 = 12 - 4z +4z-4z + 12 -12 = 12 -12-4z / -4 = 0 / -4z = 0:)

Well, you combine the like terms (-4z and 4z). -4z - 4z = -8z Now I'm not sure what to do after this because you haven't written the operation that comes before the 9, whether it's +, -, x, or /
7 + 4z = 437 + 4z -7 = 43 - 7 4z = 43 - 7 4z = 36 z = 9
4z-11=45 4z=56 z=14
4z means to multiply a number with another number.
4z + 820 is not an equation. It has no answer, because it asks no question.
4z - 1 = 9 4z = 10 (add 1 to both sides) z = 2.5 (divide both sides by 4)
4z + 2 + 5z - 3 = 9z - 1
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
