Answer: a
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
Simplify the numerator
(2x) ^3 = 8 x^3
8x^3 * 3x = 24 x^4
Simplify the denominator
(6x^2) ^2 = 36 x^4
Simplify the fraction
24x^4/ 36 x^4 =
24/36 = 2/3
x^4/x^4 =1
The fraction is 2/3 when x does not equal 0
62x=y
1860/62=30min
70 gallIons per minute, minus the 8 gallons per minute would give you a growth of 62 gallons per minute. you need 1860 gallons in total so divid that by your growth in which it'll take 30 minutes to fill up a 1860 gallon tank.
x^2-9x-6=0
Use the quadratic formula to get (9+sqrt(105))/2 or (9-sqrt(105))/2
