Answer:
16x^4+32x^3+24x^2+8x+1
Step-by-step explanation:
(2x+1)^4
(2x+1)*(2x+1)*(2x+1)*(2x+1)
X = 84

63 <= 7y
To solve for y just divide both sides by 7:
Y <= 63/7
Y <= 9
Because 63 is less than , you need to reverse the inequality sign.
The answer becomes y >=9
Now when you replace y with a number from 9 or higher the inequality will be true.

5 - 1 = 4 grams
10% of 5 = 0.5 grams per hour
4/0.5 = 8 hours
4x + 11 = k
<=> 4x = k - 11
