Answer:
1/2x^2-2x
Step-by-step explanation:
x^2+2x+1/2x^4+2x^3-2x^2-2x
(x+1)(x+1)/2x(x+1)(x+1)(x+1)
ax^2 +bx+c=0
X^2 + 2x+8=0 so a=1, b=2, c=8
Discriminat= b^2 -4ac=2^2 -4•1•8=4-32=-28
So there are no real number solutions, yet there are complex numbers solutions.
Solutions=(-b+- sqrt (discriminant))/2•a
=(-2+-i sqrt ( 2•2•7))/2
Solutia 1= -1 + i sqrt7
Solutia 2= -1 - i sqrt 7
Sam sold half as many as Odel.
That means Odel sold twice as many as Sam.
Let x = number of pizzas sold by Sam.
Then Odel sold 2x.
Altogether they sold 126
x + 2x = 126
3x = 126
x = 42
Since x is the number of pizzas sold by Sam, that is our answer.
Answer: Sam sold 42 pizzas.
y = cos x
the graph has an amplitude of 1 and a period of 2π and crosses the y-axis at 1 for x = 0 and the x-axis at 0 for x = 
Thanks for the question!
mx + nx = p
Group them with x as the GCF
x(m +n) = p
Divide both sides by m+n
x = p/m+n
Hope this helps!
