Hey!
To solve x in this equation we must first add five to both sides to get
on its own.
<em>Original Equation :</em>
<em>New Equation {Added 5 to Both Sides} :</em>
Now we must square both sides of the equation.
<em>Old Equation :</em>
<em>New Equation {Changed by Squaring Both Sides} :</em>
And now we must solve the new equation.
Step 1 - Switch sides
Step 2 - Subtract x from both sides
Step 3 - Simplify
Now we need to solve the rest of the equation using the quadratic formula.

Answer:
9.14 inches.
Step-by-step explanation:
From the question,
Assuming the diagram attached, is similar to diagram required to support the question,
From the diagram,
Applying pythagoras theorem
a² = b²+c²...................... Equation 1
Where a = 13.4 in, b = x in, c = 9.8 in.
Substitute these values into equation 1
13.4² = x²+9.8²
x² = 13.4²-9.8²
x² = 179.56-96.04
x² = 83.52
x = √(83.52)
x = 9.14 inches
Hence the distance between the rods is 9.14 inches
