$(7x + 3)(4x -5)$

$7x*4x+7x(-5)+3*4x+3(-5)$

$7*4xx-7*5x+3*4x-3*5$

$=28x^2-23x-15$

Hope this helps!

Thanks!

Which complex number is a distance of sqrt17 from the origin on the complex plane?

lions [1.4K]

Let z=x+iy be a complex number. The distance from this complex number to the origin is

$\sqrt{(x-0)^2+(y-0)^2}=\sqrt{x^2+y^2}.$

Consider all options:

A. z=2+15i, then $\sqrt{2^2+15^2}=\sqrt{229}.$

B. z=17+i, then $\sqrt{17^2+1^2}=\sqrt{290}.$

C. z=20-3i, then $\sqrt{20^2+(-3)^2}=\sqrt{409}.$

D. z=4-i, then $\sqrt{4^2+(-1)^2}=\sqrt{17}.$

Answer: correct choice is D.
