z2 + 9z + 18 = z2 + 6z + 3z + 18 = z(z+6) + 3(z+6) = (z+6)*(z+3)
Z is equal to 6. Z+2=8 8-2=6 Z=6
z/6 = -5/12, cross multiply. z*12 =-5*6 z = -30/12 z= -5/2
(z - 8) / 6 = -4 Multiply both sides by 6: (z - 8) = -24 Add 8 to both sides: z = -16
6+z = 3 z = 3-6 z = -3
y = sin6(z) dy/dz = 6*sin5(z)*cos(z) then d2y/dz2 = 6*5*sin4(z)*cos(z) + 6*sin5(z)*(-sin(z)) = 6*sin4(z)*[5*cos(z) - sin2(z)]

If z = 3, what is 5 x (6 β z)?
z / 6 = 42 Multiply both sides by 6 to get z = 42 * 6 So z =252
z2 + 9z + 18 = z2 + 6z + 3z + 18 = z(z+6) + 3(z+6) = (z+6)*(z+3)
6/z
Z is equal to 6. Z+2=8 8-2=6 Z=6
z/6 = -5/12, cross multiply. z*12 =-5*6 z = -30/12 z= -5/2
|z - 3| < 6 => 0
(z - 8) / 6 = -4 Multiply both sides by 6: (z - 8) = -24 Add 8 to both sides: z = -16
If your equation was written correctly your answer should be z = (23/379) The solution is as follows: 57-56-z-7 = 757z-6+4-50 -z-6=757z-52 -z-6+52=757z-52+52 -z+46=757z -z+46+z=757z+z 46=758z (46/758)=(758z)/758 (46/758)=z (23/379)=z
