Hi Zegroes,  I did not see you sneek on ther forum.  Why didn't you say hello   

I don't know if anyone is even on here anymore but can someone help me solve (2-4i) + 4.

You cannot solve it because there is no equal sign.  You can only simplify it.

(2-4i) + 4

= 2-4i+4

= 2+4-4i

= 6 - 4i

Yes it is, as far as I know.

Solve for x:
x^2+x-6 = 0

The left hand side factors into a product with two terms:
(x-2) (x+3) = 0

Split into two equations:
x-2 = 0 or x+3 = 0

Add 2 to both sides:
x = 2 or x+3 = 0

Subtract 3 from both sides:
Answer: |     x = 2               or x = -3
 

X^2+x-6=0

\(\begin{array}{rcl} x^2+x-6 &=& 0 \\ (x +3 )(x - 2 ) &=& 0 \end{array}\)

\(x = -3 \quad \text{ or } \quad x = 2 \)

Next time you should say "Please, I need help". OK?

Sin(37)=0.601815.......etc. It is an irrationa number, and therefore cannot be expressed as a fraction. You can approximate it to a fraction, such as 1,061/1,763=0.601815(8791832104367555303460011). Only the numbers outside the bracket are accurate. The rest of them are wrong.

b=  initial value

find missing length of 12in and 12in pythagorean theorem

H^2=12^2 + 12^2

H^2=144 + 144

H^2=288 take the square root of both sides,

H=16.97 inches-the hypotenuse.

3 = a - 12, you got it right.

a=3+12

a=15

This is what a fraction looks like: 1/2. This is called a "half". If you slice an apple in half, then you have two halves, and each half is written like this: 1/2.

Good night Hayley :)

Simplify the following:
x^2+x^2+2 x-5+3

Grouping like terms, x^2+x^2+2 x-5+3 = (x^2+x^2)+2 x+(3-5):
(x^2+x^2)+2 x+(3-5)

x^2+x^2 = 2 x^2:
2 x^2+2 x+(3-5)

3-5 = -2:
2 x^2+2 x+-2

Factor 2 out of 2 x^2+2 x-2:
Answer: |   2 (x^2+x-1)
 

Ops... i forgot to click the button to sumbit it. My bad!

Going to bed! nighht! 

Solve for x:
64 = 14 x+3 (2 x+4)

3 (2 x+4) = 6 x+12:
64 = 6 x+12+14 x

Grouping like terms, 14 x+6 x+12 = (14 x+6 x)+12:
64 = (14 x+6 x)+12

14 x+6 x = 20 x:
64 = 20 x+12

64 = 20 x+12 is equivalent to 20 x+12 = 64:
Answer: |  x=13/5

Some claim it was an Anonymous Cow whose name is lost to History.......others claim it was the obscure figure, Cal Cium.......yet, others attribute it to the little-known scientist, Lewis Pasture.

The latter seems most likely..........
