Final answer:

To make 30 biscuits, you would need 5 cups of flour.

Explanation:

To find out how much flour is needed to make 30 biscuits, we can set up a proportion using the given information. Since the recipe calls for 2 cups of flour to make 12 biscuits:

2 cups of flour = 12 biscuits

Let 'x' represent the amount of flour needed to make 30 biscuits:

x cups of flour = 30 biscuits

Using cross multiplication, we can solve for 'x':

2 * 30 = 12 * x

60 = 12x

x = 5 cups

For this case we have the following equation:

Rewriting the equation we have:

Then, we must factor the equation:

We are looking for two numbers that are equal to 7 and multiplied equal to -18.

We have then:

Answer:

An equation that could be used to solve by factoring is:
