Question

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

Answer 1

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'.

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.
