Hey!
The first step to solving this equation would be to subtract 5 from both sides of the equation.
<em>Original Equation :</em>

- 8x + 16 = 5
<em>New Equation {Added Subtract 5 to Both Sides} :</em>

- 8x + 16 - 5 = 5 - 5
Now we solve our new equation.
<em>Old Equation :</em>

- 8x + 16 - 5 = 5 - 5
<em>Solution {Old Equation Solved} :</em>

- 8x + 11 = 0
The next step would be to solve with the quadratic formula.
<em>Quadratic Equation ( 1 ) :</em>

<em>Quadratic Equation ( 1 ) {Solved} :</em>
4 +

<em>Quadratic Equation ( 2 ) :</em>

<em>Quadratic Equation ( 2 ) {Solved} :</em>
4 -

<em>So, our final solutions for the equation

- 8x + 16 = 5 are...</em>
x = 4 + 
<em>and </em>
x = 4 - 
Hope this helps!

Answer:
Step-by-step explanation:
Write it out: A = 1/2(bh)
substitute values: 232 = 1/2(16b)
Simplify: 232 = 8b
Divide each side by 8: b = 29
The base is 29 millimeters
