Justify "<span>x2 = 25 is {±5}"

First, please write x^2, not x2.

</span><span>x^2 = 25; solve for x.  Take the sqrt of both sides.  Must write "plus or minus " in front of the sqrt of 25:

x^2 = 25 becomes x = plus or minus 5, so x: {-5, 5}</span>

What is x over 5 - 68 = -95
vagabundo [1.1K]
Hello, there!


This would look like: x/5 - 68 = -95

First, we want to isolate the x.

x/5 - 68 = -95
      +68    +68

 x/5 = -27

Now, we will work backwards to find the x.

-27 * 5 = x

-27 * 5 = -135

x = -135

Your answer is -135


I hope I helped!

Let me know if you need anything else!

inn [45]

Answer: 3617.28 cubic millimeters.

Step-by-step explanation: I used the formula of a sphere since a gumball is a shape of a sphere and plugged the radius into the formula.

I got that the volume of a single gumball is 288π cubic millimeters.

Since there are 4 gumballs, i multiplied the volume by 4.

The total volume of the four gumballs add up to be 1152π .

Lastly, I multiplied 1152 by pi

and got the answer to be 3617.28 cubic millimeters
