Well there aint no whole number for this thee are 85 in each bag, so what is 680 divide 12 that is 56.6 like i said not a whole number so round to nearest.
-4x^4 - 15x^2 + 1 - 19/x^2 is your answer
Hope I helped :)
Answer:
x = sqrt(29)/2 - 3/2 or x = -3/2 - sqrt(29)/2
Step-by-step explanation by completing the square:
Solve for x over the real numbers:
x^2 + 3 x - 5 = 0
Add 5 to both sides:
x^2 + 3 x = 5
Add 9/4 to both sides:
x^2 + 3 x + 9/4 = 29/4
Write the left hand side as a square:
(x + 3/2)^2 = 29/4
Take the square root of both sides:
x + 3/2 = sqrt(29)/2 or x + 3/2 = -sqrt(29)/2
Subtract 3/2 from both sides:
x = sqrt(29)/2 - 3/2 or x + 3/2 = -sqrt(29)/2
Subtract 3/2 from both sides:
Answer: x = sqrt(29)/2 - 3/2 or x = -3/2 - sqrt(29)/2
Answer:
9p+3r−7
Step-by-step explanation:
=3r+12p+−7+−3p
Combine Like Terms:
=3r+12p+−7+−3p
=(12p+−3p)+(3r)+(−7)
=9p+3r+−7
X=7/64 you multiply them by x first then do the math
