Select the correct answer.

The product of two integers is 112. One number is four more than three times the other. Which of the following equations could be used to find one of the numbers?

A. [tex]3x^2 + 4x = 112[/tex]
B. [tex]3x^2 + 4 = 112[/tex]
C. [tex]4x^2 + 3x = 112[/tex]
D. [tex]4x^2 + 3 = 112[/tex]

Answer :

Sure! Let's break down the problem step by step to find the correct equation you can use to solve for one of the numbers.

1. Understanding the Problem:
- We are given that the product of two integers is 112.
- One of the numbers is four more than three times the other number.

2. Define the Variables:
- Let's call the first integer [tex]\( x \)[/tex].
- According to the problem, the second integer would then be [tex]\( 3x + 4 \)[/tex] (since it is four more than three times [tex]\( x \)[/tex]).

3. Set Up the Equation:
- Since the product of the two integers is 112, we can write the equation as:
[tex]\[
x \times (3x + 4) = 112
\][/tex]

4. Simplify the Equation:
- Distribute [tex]\( x \)[/tex] to get:
[tex]\[
3x^2 + 4x = 112
\][/tex]

This corresponds to the equation shown in option A: [tex]\( 3x^2 + 4x = 112 \)[/tex].

So, the correct equation that could be used to find one of the numbers is option A: [tex]\( 3x^2 + 4x = 112 \)[/tex].
