Calculus

If you mean Microsoft's backup file extension, it's function is to make PCs and Macs even more incompatible, thus putting more money into Bill Gates' pocket.

z = 2

Factorised as (z - 2)(z - 2) = 0

Addition is commutative

are you sure from this equation ?

x^2 + 9x + 11

____________ = zero

x + 7

or there is no zero ??

please be sure from the x^2 + 9x + 11 ???

1.5/6.5 = 3/13 and 6.5/1.5 = 13/3

The equation is : 39x2 - 178x + 39 = 0

x = {-(-178) ± sqrt[(-178)2 - 4*(39)*(39)]}/(2*39)

= {178 ± sqrt[25600]}/78

= {178 ± 160}/78

= 18/78 or 338/78

= 3/13 or 13/3, as required.

----

This is what I would add, although it might be unnecessary:

As Mehtamatics indicates the solutions are 3/13 and 13/3. This implies that the equation can be written as the product of factors ( x - 3/13 ) and ( x - 13/3 ).

( x - 3/13 )( x - 13/3 )

= x2 - ( 39 + 169 ) x / 39 + ( 3/13 ) ( 13/3 )

= x2 - 178 x / 39 + 1

= 39 x2 - 178 x + 39 = 0

The required condition is a*b ≠ 0. That is equivalent to the requirement that neither a nor b is 0.

ordered pair, or coordinates of a point

It is 2 terms of an algebraic expression in the form of: 3x+731

9x plus 3 plus 2x plus 1 will result to 11x+4(first collect the like terms).

Y. B. Mokashi has written:

The result obtain from the equation 4 plus -1 -21 is -18.

(956 - 830) x (908 x 291 + 598) =

(126) x (264228 + 598) = 33368076

sqare root of 145. my approximation... 12.0398 cm

A = 3.14(Pi) x r2 So, if radius is 4 inches, then A = 3.14 x (4 in. x 4 in.)

A = 3.14 x 16

A = 50.24 in. 3.14 is just an approximation to Pi of course, we could use more digits of Pi if we need it.

There is none, it continues to multiply and go on and on.

The answer depends on 1 billion WHAT! And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

When pi is written digitally, it never ends and never repeats, because it is an infinite number.

This is just the beginning, though: 3.14159265358979323846…

most likely 18

It depends on what you are trying to solve for. Here is a solution for x... y = mx + b y - b = mx (y - b) / m = x Note: If m is zero, then there is no solution, because the line is horizontal

Each side can have any length in the range (0, 12.9) units. The only restriction is that the sum of the seven sides must be 12.9 units.

-2

Divide both sides by -14

x = 4
