Answer:
6(2 - 5k^4).
Step-by-step explanation:
12k^0 - 30k^4
Now k^0 = 1 so the polynomial becomes
12 - 30k^4
= 6(2 - 5k^4).
$68 is discounted from the regular price.
To find this, you first divide 80% by 100 to get 0.8 (the decimal form of the percentage). Then, simply multiply 0.8 by 85 (or vise verse) to get $68. Since the question is asking for how much is discounted from the regular price, the final answer would be $68.
I hope this helps!
144, 4:6 simplifies to 2:3, if you divide 96 by 2 you get 48, and 48 x 3 = 144
2x+10, multiply to two each term x and 5
