twice the difference between a number and 10 is equal to 6 times the number plus 14. what is the number?

1 answer:

4 0

Let the number be n. Then 2(n-10) = 6n + 14.

Multiplying out the left side, 2n - 20 = 6n + 14. Thus, -34=4n, and n = -17/2.

PLEASE HELP WITH THIS ONE QUESTION

Genrish500 [490]

$Hello$ $There!$

$2x^4+16x=0$

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

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

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!!
