Np! I just like to help people at times!  (If i know the answer lol)

9+10=19

Thanks, Rosey......!!!

Pi (it's a Greek letter) is the ratio of any circle's circumference to its diameter. It's usually expressed as 3.14, but is in fact a nonrepeating, nonterminating decimal number. 

3.14159265358979 should be more than sufficient for any use outside the most advanced math classes.

1/3(4x-6)+3  =

(4/3)x - 6/3 + 3  =

(4/3)x - 2 + 3 =

(4/3)x + 1

Nobody cares!!! Just kidding happy birthday!

Ginger Ale,

How can you find a two year old post so fast, and how can you even remember what to look for??!!!!

Also, how can you edit a post after an hour. I’m lucky if I can do it at all.

Good luck with your 'essay'  !

Happy Birthday's Eve Eve !!

To ADD fractions you have to get a 'common denominator' 

A good one in this case would be 16

1/8 + 1/16 =

2/2 (1/8) + 1/16=

2/16 + 1/16 = 3/16

what is 1/8 + 1/16 = 2/16 + 1/16 =3/16

Using Pythagorean Theorem

a^2 + b^2 = c^2   where  'a' and 'b' are the short sides (legs) and 'c' is the hypotenuse (the longest side)

Example  :   right triangle with  legs of  4  and 'x'  and hypotenuse 5

4^2 + x^2 = 5^2

16 + x^2  = 25

x^2 = 9

x= 3 = this 'missing' leg size.....

T (25) = .0002(25)³ - .0114(25)² + .0158(25) + 104   =  100.395°

-(5/4)^3+4(1/8-3/4)^2  =

-(125/64) + 4 (1/8 - 6/8)^2  =

-(125/64)  +  4 (-5/8)^2  =

-(125/64) + 4 (2564)  =

-125/64   +  100/64  =

-25/64

Thank you! 

See the solution under your first post.

8+3*x=2^2+x^2

8 + 3x  = 4 + x^2         subtract 8 + 3x from both sides

0  = 4 + x^2 - 8 - 3x       simplify

0 = x^2 - 3x - 4        factor

0 = ( x - 4) ( x + 1)         

Set both factors to  0

x - 4  = 0                             and                          x + 1  = 0

add 4 to both sides                                          subtract 1 from each side

x = 4                                                                   x = -1

And those are the two solutions

Solve for x:
3 x+8 = x^2+4

Subtract x^2+4 from both sides:
-x^2+3 x+4 = 0

The left hand side factors into a product with three terms:
-((x-4) (x+1)) = 0

Multiply both sides by -1:
(x-4) (x+1) = 0

Split into two equations:
x-4 = 0 or x+1 = 0

Add 4 to both sides:
x = 4 or x+1 = 0

Subtract 1 from both sides:
Answer: |x = 4               or              x = -1

4 years = 48 months.....so....

$10 per month  x 48 months  =   $480

Happy Birthday, Rosala..........!!!!!!!

2/4 = sin (theta)         ..... 2/4 = 1/2.....

1/2 = sin(theta)      use the sine inverse to find theta

arcsin (1/2)   = theta  = 30°  or , in radians,  pi/6

{2-9[2+(3+1/2)^2]}-4  =

{ 2  - 9 [ 2 + (7/2)^2]} - 4  =

{ 2 - 9 [2 + 49/4) ] } - 4 =

{2 - 9 [ 57/4] } - 4 =

{ 2 - 513/4} - 4  =

{ 8/4 - 513/4 }  - 4  =

-505/4 - 4  =

-505/4 - 16/4  =

-521/4  =  - [ 130 + 1/4 ]

Congratz!!
