Susan opened a college savings account 4 years ago. She opened the account with an initial deposit of $3,000. Starting the next year, she deposited $1,000 on the same day each year. The account earns interest at an annual rate of 4.15% and is
compounded annually. Susan hopes to have earned enough interest to pay for her first year of college tuition, which costs
$7,100. What is the difference between her ending balance after 4 years and the cost of her tuition?

Write as a product of 2 binomials and a monomial (factor out as much as possible from each binomial). ! i do not understand, any is appreciated : ) whoever gets the best answer recieves brainliest and points! (4x–12x²)(16y³+12y²)

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
