i just answered it.......see the other post

1/2 (x-5) = x/4   let us multiply both sides by 4 to clear the fractions....so we have...

2(x - 5) = x        simplify

2x - 10   = x      subtract x from both sides and add 10 to both sides

x = 10

The diagonal of any square = S*sqrt(2)   where S is the side length of the square

So   80* sqrt(2) = about 113.14 ft

sqrt(12) =  sqrt(4 *3)  = sqrt(4) * sqrt(3)    =    2*sqrt(3)

.092 x 59.95 = about $5.52

x + 4 <  9     subtract 4 from both sides

x <  5

Yep...we need the brackets because the way you have it written is interpreted as:

1/x^2   - 1   >=    1/x - 1           [ the 1's  are separate from the fractions ]

Instead of what you intended which is :

1/ [x^2 -1 ]   >=  1 /[ x - 1 ]

Brackets and parentheses are important......!!!!

Got no idea.....it's always been here since I arrived.....I assume it will be here after I've left....!!!!

5/9(50 - 32 )  =

(5/9) (50- 32)  =

(5/9) (18)  =

[ 5 * 18 ] / 9  =

90/ 9 = 

10

Velocity is the derivative of the position function, and acceleration is the derivative of the velocity function.
