The answer is $820.
I found this by 0.8x = 656
(Remember, a 20% discount means that it costs 80%, or 0.8, of the original price)
Then, divide 0.8 on both sides:
0.8x/0.8 = 656/0.8
This leaves you with:
x = 820
Answer: a & b
<u>Step-by-step explanation:</u>
t³(8 + 9t) - (t² + 4)(2 - 3t)
= 8t³ + 9t⁴ - (2t² - 3t³ + 8 - 12t)
= 8t³ + 9t⁴ - 2t² + 3t³ - 8 + 12t
= 9t⁴ + 11t³ - 2t² + 12t - 8
a) The simplified expression is a polynomial. TRUE
b) The simplified expression has a constant term. TRUE
c) The simplified expression is cubic. False - it is degree 4
d) The simplified expression has four terms. False - it has 5 terms
e) The simplified expression is a trinomial False - it has 5 terms
The only other way is in improper fraction form. Written this way it would look lik this: 20/3. Hope this helps.
