Neither.

That would be very hard to answer, because it's not.

(x + y)2 = x2 + y2 + 2xy

the answer is 0

Yes, but only when x is equal to zero.

It is the equation of a circle with radius of 6

and its center at the origin.

It works out that the point of intersection is at (-4, -3.5) on the Cartesian plane.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals". It is therefore impossible to work out what the equation might be.

It is easy if that side is the one that is x!

It is not possible to give a sensible answer to the question because you have not bothered to specify what x is.

It is: (x+9)(x-1) when factored.

derivative of 9[sin(x)]^2 is found by first letting u(x)=[sin(x)]^2. Note that sin2x = [sin(x)]^2, and the ^2 means raising the base to the exponent 2.

Find the d(9u(x))/dx using the chain rule.

d( 9u(x) )/dx = (d(9u)/du)(du/dx ) , by the chain rule.

So we need:

d(9u)/du = 9ulog(9)

du/dx = d( [sin(x)]^2 )/dx = 2sin(x) d( sin(x) )/dx = 2sin(x)cos(x)

Puttin this together gives:

d( 9u(x) )/dx = 9u(log(9)) 2sin(x)cos(x)

Now substitute in u(x) = [sin(x)]^2.

d( 9u(x) )/dx = 9[sin(x)]^2(log(9)) 2sin(x)cos(x)

= 2 log(9) 9[sin(x)]^2sin(x)cos(x) or

= log(9) 9[sin(x)]^2sin(2x)

Quadratic - the degree is two.

double 4 times 4

(0,2) is one possible answer.

If you require more information, send me a message, I assume that you know basic calculus but haven't used in in applications like this.

Do you mean,

2 + 3^x = 245 ??

2 + 3^x = 245

subtract 2 from each side

3^x = 243

use natural logs ( I always do, though you can use logs )

ln(3^x) = ln(243)

you have the right in this operation to bring the exponent before the natural log

x(ln3) = ln(243)

divide

x = ln(243)/ln(3) ( not ln(243/3) !!!! )

x = 5.493061443/1.098612289

x = 5

----------check

2 + 3^5 = 245

2 + 243 = 245

245 = 245

Possibly, but I would need to know what x, a and c were.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And use ^ to indicate powers (eg x-squared = x^2).

Positive (Plus) times Negative (Minus) always equals a negative (minus).

are you talking about obtuse (91-179), a straight angle (180), or reflex (181-359)

y = 6*x1/2 - 3x

dy/dx = 6*(1/2)*x-1/2 - 3

= 3x-1/2 - 3 = 3/sqrt(x) - 3 or 3[1/sqrt(x) - 1]

X -8

same as,

1/X8
