Answer:
The correct option B) 4.
Step-by-step explanation:
Consider the provided equation.
[tex]5x - 20 = 0[/tex]
To find the zero simplify the above equation as shown
Add 20 from both the sides.
[tex]5x - 20+20 = 20[/tex]
[tex]5x= 20[/tex]
Divide 5 from both the sides.
[tex]\frac{5x}{5}=\frac{20}{5}[/tex]
[tex]x=4[/tex]
Thus, the zero of the equation is [tex]x=4[/tex].
Hence, the correct option B) 4.
