$Hello$ $There!$

$2x^4+16x=0$

$Factor:$ $2x^4+16: 2x(x+2)(x^2-2x+4)$

$2x(x+2)(x^2-2x+4)=0$

You got to used the Zero Factor Principle:

$x=0$ $or$ $x+2=0$ $or$ $x^2-2x+4=0$

$Solve: x+2=0:x=-2$

$Solve: x^2-2x+4=0: x=1+\sqrt{3}i,x=1-\sqrt{3} i$

ANSWER:

$x=0,x=-2,x=1+\sqrt{3} i,x=1-\sqrt{3} i$

Hopefully, this helps you!!

14 books in 3 months is 35%
all of books is 100%

14- 35%
x- 100%
we calculate from proportions, crosswise:
$x=\frac{14*100}{35}=\frac{1400}{35}=40$

Answer: Benito sign up to read 40 books.

he entry fee to the fair is 4.00 . each rides requires a ticket that cost 0.50 heidi spent a total 12.00 how many ticket did hei

Hey there!

Set up an equation. This would be 4+0.5x=12. You have to get x by itself, so subtract 4 on each side. You get 0.5x=8. Divide by 0.5 on each side to get x=16. Heidi purchased 16 tickets.

I hope this helps!
