Which of the following is a solution of x^2 - 2x = -8?

1 answer:

6 0

X^2-2x=-8 add 1 to both sides

x^2-2x+1=-7 now the left side is a perfect square

(x-1)^2=-7 take the square root of both sides

x-1=±√-7 add 1 to both sides

x=1±√-7 which is

x=1±i√7 so

x=1+i√7 and 1-i√7

The value of x after the simultaneous rotation and translation of pentagon A to create pentagon B is 110°

<h3>What is the translation of plane figures?</h3>

A plane figure translation is an isometry that translates each position of the figure at a distance and in a direction indicated by the vector.

It is also regarded as a sort of transformation that involves sliding each point in a plane figure at an identical distance in a similar direction.

From the attached image, the value of x after the simultaneous rotation and translation of pentagon A to create pentagon B is 110°.
