2*x2 when x = 2 is 2*(-2)2 = 2*(+4) = 8

d/dx(cos x)

= -sinx

Increase the length of the pendulum

3x3 - 10x = 17x divide by x to both sides
3x2 - 10 = 17 add 10 to both sides
3x2 = 27 divide by 3 to both sides
x2 = 9
x = ±√9
x = ±3

The curve given by (t-sinh(t)cosh(t), 2 cosh(t)), t real.

x2 + 7x = 2x2 + 6

x2 - 2x2 + 7x = 6

-x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0

y = 10x + 14

y-int. = 14

x-int. = -14/10

slope = 10

You need to find two factors of 5*672 = 3360, whoxe difference is 4: these are 56 and 60.

Then 5x2 - 4x - 672 = 5x2 - 60x + 56x - 672 = 5x(x - 12) + 56(x - 12)

= (x - 12)*(5x + 56)

In the equation 43X +2=5X, X=-1/19.

There is none because it's not an equation

(a2 + 5a + 6)/(a - 2) = (a + 2)*(a 3)/(a - 2) which cannot be simplified further.

It can, however be written as (a2 - 2a + 7a - 14 + 20)/(a - 2)

which is (a + 7) + 20/(a - 2)

The first step is to ensure that the symbol between 2x and 4 is visible to whoever is trying to answer the question. Unfortunately this browser is not up to that task so you will need to re-submit the question with "plus" or "minus" etc replacing symbols.

6y + 8 = 32

6y + 8 - 8 = 32 - 8

6y = 24

6y/6 = 24/6

y = 4

Given the information in the question, there is no need for any inequality. the flat surface can be described as an equality.

Outer diameter = one and a half inches => outer radius = 0.75 inches.

Inner diameter = three fourths inches => inner radius = 0.375 inches.

Area = pi*(0.752 - 0.3752) square inches.

So one possible set of inequalities is 0 < area < 1,000,000,000 sq inches!

the inverse of x+3

x+x=2x

6x - 3x = 5x - 10x + 12

6x - 3x - 5x + 10x = 12

8x = 12

8x/8 = 12/8

x = 12/8 = 3/2

x = 1.5
