Stacy has $25 in her savings account. To save more money, Stacy is selling
lemonade for $0.50. She wants to have
a minimum of $150 in her account.
Which inequality represents this
situation?

In -2^2 since the negative sign is not in parentheses you would solve it as 2×2=4 and then have the negative sign so it would be -4. With the parentheses you are saying that the term you are squaring is (-2) and two negatives make a positive so it would be (-2)×(-2)= 4.
