If x-y = 40 and x+y = 70, then what is the value of x squared -y squared ?

OlgaM077 [116]

Let's see what to do buddy...

____________________________

Reminder:

$(a + b)(a - b) = {a}^{2} - {b}^{2}$

So we need to just Multiply above equations like this :

$x + y = 70$

$x - y = 40$

$(x + y)(x - y) = 70 \times 40$

${x}^{2} - {y}^{2} = 2800$

____________________________

And we're done.

Thanks for watching buddy good luck.

What is the antiderivative of 4/e^4x?

Andrews [41]

$\displaystyle
F=\int \dfrac{4}{e^{4x}}\, dx\\
F=4 \int e^{-4x}\, dx\\
F=4 \cdot\left(-\dfrac{1}{4}e^{-4x}\right)+C\\
F=-e^{-4x}+C$
