Answer:
4/6
Step-by-step explanation:
Expand (x+2)^2: x^2 + 4x + 4 : remember that (a+b)^2 = a^2 + 2ab + b^2
So: x^2 + 4x + 4 - x^2 = 60
Answer:
y x (0.75+ 5(
Step-by-step explanation:
Hmmm what is now discounted? well, let's assume it sells normally for 499 and is discounted today at 25%, how much is that?
well, if we take 499 to be the 100, how much is 25%?

now, applying the sales tax to the discounted price.
if we take 374.25 to be the 100%, how much is 6.5%?

so, the total cost will then be 374.25 + t.
