Answer:
if you want to factorise it answer will be : (x+y)^2 - 4^2
and if you have to expand it anwer will be x^2 + y^2 + 2xy -16
300 x 700 = 210,000 square feet
600 x 1400 = 840,000 square feet
840,000 - 210,000 = 630,000 square feet difference

Answer:
$83.04
Step-by-step explanation:
1. Add up all the prices (49.99, 13,99, 13.99) = 77.97
2. Tax is 6.5% (.065 in decimal form)
3. Multiply 77.97 * .065 = 5.06805
4. 5.06805 rounds to 5.07
5. Add the total purchase (77.97) to the tax (5.07) = 83.04
