Question

Create a problem that would have the answer 3x+12

Answer 1

Answer:

Problem:

Consider a rectangle such that the width of the rectangle is 12 more than thrice its length. Find a formula for the width in terms of its length. Take length as 'x'.

Step-by-step explanation:

Consider a rectangle such that the width of the rectangle is 12 more than thrice its length. Find a formula for the width in terms of its length.

Let the length be 'x'.

Therefore, as per question, width is 12 more than thrice the length.

Thrice the length means $3x$. 12 more means adding 12 to the result.

Therefore, the width of the rectangle is $3x+12$.

So, the above question expresses the width of the rectangle as $3x+12$ which is the required answer.
