Step-by-step explanation:
The given statement is;: 'I think of a number, multiply it by 3, add 4 & square the result.'
At first, let's take the unknown number as 'x' . (asked in the question).
So, the number we think about = x
Now, we need to multiply it by 3. So,
- 3 * x = 3x
In the next part, we need to add 4 to it so,
- 3x + 4
Now, by squaring the result, we'll get the expression as,
- <u>(3x + 4)²</u>
