Solve for x over the real numbers:
x^3 (x^2 - 4) = 0
Split into two equations:
x^3 = 0 or x^2 - 4 = 0
Take cube roots of both sides:
x = 0 or x^2 - 4 = 0
Add 4 to both sides:
x = 0 or x^2 = 4
Take the square root of both sides:
Answer: x = 0 or x = 2 or x = -2
Answer:
Step-by-step explanation:
let pickle bought by alexa =x
then according to given condition ,
pickle bought by Tom= (1/3) of Alexa
pickle bought by Tom= (1/3) x
hence also given
totall pickle cost = Tom cost + alexa cost = 56p
(1/3)x+x=56
taking L.C.M
(4/3)x=56
x=56*3/4
x=42 p
so it means,
<h2>
Alexa cost = x = 42p</h2><h2>
Tom cost = (1/3)x= (1/3)*42 = 14 p</h2>
Pi feet squared (I hope I helped!)
Answer:
the standard form of the equation is: a. y=7x^2-42x+67
