Answer:

$p=12x-10$

Step-by-step explanation:

Perimeter is just adding all of the sides' lengths together, so we can put all of them into one big equation and then combine like terms.

$p=x+(2x+5)+(6x-17)+(3x+2)\\p=12x-10$

Hope this helps!

Find all complex numbers $z$ such that $z^4 = -4.$

patriot [66]

Converting -4 to polar form gives $-4=4\exp(i\pi)$ .

Then the 4th roots of -4 would be the numbers

$4^{1/4}\exp\left(i\dfrac{\pi+2k\pi}4\right)$

where <em>k</em> is taken from {0, 1, 2, 3}.

So we have

$z_1=4^{1/4}\exp\left(\dfrac{i\pi}4\right)=\sqrt2\left(\cos\dfrac\pi4+i\sin\dfrac\pi4\right)=1+i$

$z_2=\sqrt2\left(\cos\dfrac{3\pi}4+i\sin\dfrac{3\pi}4\right)=-1+i$

$z_3=\sqrt2\left(\cos\dfrac{5\pi}4+i\sin\dfrac{5\pi}4\right)=-1-i$

$z_4=\sqrt2\left(\cos\dfrac{7\pi}4+i\sin\dfrac{7\pi}4\right)=1-i$
