Answer:
3 + 4x
Step-by-step explanation:
Let "a number" be x.
Therefore "four times a number" is 4 multiplied by x which is 4x.
Now add 3 for "3 plus".
3 + 4x
To effectively determine the correct answer, it would be helpful to write this into an algebraic expression. We let x as the number. We do as follows:
<span>Four times the square of a certain number increased by 6 times the number equals 108.
4x^2 + 6x = 108
The numbers can be either of the following since the equation generated was a quadratic equation which has two roots.
x = 4.5
x = -6 </span>
