Which of the following are solutions to the following equation?

Alecsey [184]

Answer:

x=-7

x=7

Step-by-step explanation:

we have

$2x^{2}-98=0$

Solve for x

Adds 98 both sides

$2x^{2}-98+98=0+98$

$2x^{2}=98$

Divide by 2 both sides

$2x^{2}/2=98/2$

$x^{2}=49$

take square root both sides

$x=\pm7$

therefore

The solutions are

x=-7

x=7

When using distributive property for this it’s gonna be 5(5.75+4.25)
So 5•5.75=28.75
5•4.25=21.25
So then 28.75+21.25=50

-2

Divide each term (-4x = 8 by -4)

Cancel the common factor of -4

x = 8/-4

THEN DIVIDE

x=-2

Not sure how to do this. (I'm aware this is wrong lol)

I think the answer is 80 degrees. Think about it like you're moving the chunk with 100 degrees already filled in, to the space where you're trying to find the amount since they're the same. Vertical angles are supplementary and are equal to 180. So, 100+x = 180. x would equal 80 degrees.
