What is the length of a blackboard whose breadth is 8cm and diagonal is 10cm?

Step 1: Subtract 1 from both sides of the equation. 2x + 1 = 15; 2x = 15 − 1; 2x = 14 Step 2: Divide both sides by 2 to solve for x. 2x/2 = 14/2; x = 7 Step 3: Compare the result with the given options. The calculated value x=7 matches option (d). The final answer is d) 7.

Solved: What is the length of a blackboard whose breadth is…

Subtract 1 from both sides of the equation.
$2x + 1 = 15$ $2x = 15 - 1$ $2x = 14$
Divide both sides by 2 to solve for $x$ .
$\frac{2x}{2} = \frac{14}{2}$ $x = 7$
Compare the result with the given options.
The calculated value $x=7$ matches option (d).

The final answer is $\text{d) 7}$ .
