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 :

To solve the problem, we need to find an equation that helps us determine one of the numbers that fits the given conditions:

1. Product of two integers is 112: Let's call one of the integers [tex]\( x \)[/tex]. Therefore, the product is given by multiplying this number with another integer.

2. One number is four more than three times the other: If we let [tex]\( x \)[/tex] be one of the numbers, then the other number would be [tex]\( 3x + 4 \)[/tex].

Now let's form the equation based on these conditions:

- The product of [tex]\( x \)[/tex] and [tex]\( 3x + 4 \)[/tex] must equal 112.
So, we set up the equation:
[tex]\[
x \times (3x + 4) = 112
\][/tex]

- Expanding the equation:
[tex]\[
3x^2 + 4x = 112
\][/tex]

The equation that matches this expanded form is:
- Option A: [tex]\( 3x^2 + 4x = 112 \)[/tex]

This is the correct equation to use for finding one of the numbers based on the given conditions.
