Question
4000h-9
Find the roots
h=\frac{9}{4000}
Alternative Form
h=0.00225
Evaluate
4000h-9
To find the roots of the expression,set the expression equal to 0
4000h-9=0
Move the constant to the right-hand side and change its sign
4000h=0+9
Removing 0 doesn't change the value,so remove it from the expression
4000h=9
Divide both sides
\frac{4000h}{4000}=\frac{9}{4000}
Solution
h=\frac{9}{4000}
Alternative Form
h=0.00225
