Transcript text: Write an equation that says that the length of the green line is equal to the length of the black line. Combine like terms.
Then solve for C .
Equation: $\square$
$\mathrm{e}=$ $\qquad$
Solution
Solution Steps
Step 1: Formulate the equation
The green line has length $c$. The black line spans from 1 to 9, which has length $9-1 = 8$. Therefore, the equation is $c=8$.
