$\dfrac{x-1}{x^2+2x+1}\cdot\dfrac{x^2-1}{x+1}\\\\=\dfrac{(x-1)(x-1)(x+1)}{(x+1)^2(x+1)}\\\\=\dfrac{x^2-2x+1}{x^2+2x+1}$

Find all the antiderivatives of the following function. Check your work by taking the derivative.

Rom4ik [11]

$\int 10e^x dx = 10 \int e^x dx = 10 e^x + C$

The first step, factoring out the constant 10, is due to the Constant Multiple Rule:

$\int k \cdot f(x) dx = k \cdot \int f(x) dx$

The derivative of the natural exponential function is itself! $\frac{d}{dx} \left( e^x \right) = e^x$ . Reversing this,

$\int e^x dx = e^x + C$

In rhombus ABCD, the diagonals AC and BDintersect at E. If AE=5 and BE=12, what is thelength of AB?

hram777 [196]

Diagonals that bisect each other are perpendicular and form a right angle.

AEB is a right triangle.

We can apply the Pythagorean theorem:

c^2 = a^2+b^2

Where c is the hypotenuse (longest side) and a and b the other 2 legs.

Replacing:

AB^2 = AE^2+BE^2

AB^2 = 5^2+12^2

AB^2 = 25+144

AB^2 = 169

AB=√169 = 13

Lenght of AB= 13
