Answer:
16
Step-by-step explanation:
4 x 10 = 40
6 x 4 = 24
40 - 24 = 16
Z=1/5
Subtract 85 from both sides which gets you 25z=5.
Divide both sides by 25 which is z=5/25
Simplify which gives us the answer z=1/5.
Answer:
x=4, x=3
B is correct.
Step-by-step explanation:
Given: 
Using middle term splitting factor the left side equation.


Equate each factor to 0 and solve for x
x-4=0 or x-3=0
x=4 and x=3
Hence, The solution of the equation is 4 or 3
