The answer is 4 because k+2 would be 2 then times by 6 which is 12 then subtract 8 would be 4
51) 5x-1=0 and x+6=0
5x=1, x=1/5 and x=-6
2 solutions x=1/5 and x=-6
52)x(2x+3)=0
2x=0 and 2x+3 =0
x=0 and x=-3/2=-1.5
53) x(5x-1)=0
x=0 and 5x-1=0
x=0 and x=1/5
54) z(4z+7) =0
z=0 and 4z+7=0
z=0 and z= - 7/4 = -1.75
z=0 and z=-1.75
Answer: 0.75
Step-by-step explanation:
-4.125/-5.5 = 3/4 or 0.75
-4.125/0.75 = -5.5
