Juan ran the lemonade stand for 3 more days. Each day, he used the money from sales to purchase more lemons, cups, and sugar to
make more lemonade. On day 2, he earned $16 and spent $7 on supplies. On day 3, he earned $22 and spent $12. The expression 16 – 7 + 22 – 12 can be used to model the situation for these 2 days. Identify the expression that uses adding the additive inverse to rewrite the expression.
–16 + (–7) + (–22) + (–12)
–16 + 7 + (–22) + 12
16 + (–7) + 22 + (–12)
16 + (–7) + 22 + 12
When the radicals of the quadratic equation (also known as the discriminant) is a positive number that is not a perfect square, the equation has 2 irrational roots
