$u + 2 = - 8 \\ = > u = - 8 - 2 \\ = > u = - 10$

<h2>Answer: u = -10</h2>

Step-by-step explanation:

We are given the equation <em>u + 2 = -8</em>, and we need to find the value of <em>u</em>. In order to do that, u needs to be by itself on one side of the equation, and numeral by itself on the other side.

The way to do this is by subtracting <em>2 </em>from each sided of the equation. This successfully isolates u and gives us the equation <em>u = -10</em>, which is our answer.

$u + 2 = -8$

$u + 2 -2= -8 -2$

$u=-10$

Hope this helps! Have a great day!

you multiply it as you would regular numbers and then you count the places that the decimal is in front of. in this case it would be 2 numbers, then in the number you got by multiplying, move the decimal 2 places up

Solve this quadratic equation using the quadratic formula. 2x 2 - 2x = 1

ira [324]

Answer:

( 2 + √3 ) / 2, ( 2 - √3 ) / 2

Step-by-step explanation:

2x^2 - 2x = 1

2x^2 - 2x - 1 = 0

Here,

a = 2

b = - 2

c = - 1

D = b^2 - 4ac

D = ( - 2 )^2 - 4 ( 2 ) ( - 1 )

= 4 + 8

D = 12

x = - b ± √D / 2a

= - ( - 2 ) ± √12 / 2 ( 2 )

= 4 ± 2√3 / 4

= 2 ( 2 ± √3 ) / 4

= 2 ± √3 / 2

x = ( 2 + √3 ) / 2, ( 2 - √3 ) / 2

A sphere's radius is multiplied by 3. How is its surface area affected?

Montano1993 [528]

Answer:

Step-by-step explanation:

For all shapes, the surface area will go up by a factor of 9 (3^2). This is true of spheres, cones, cubes, pyramids, torusses, everything.

The surface area of any body is proportional to the square of any linear dimension. Triple a linear dimension and you get a 9 fold increase in surface area. This is as true for pretzels as it is for spheres and cubes.
