Since I just realized that you meant x^2-2x+1, let me evaluate this step by step:
x^2-2x+1
((-3)^2)-(2(-3))+1
9-(-6)+1
9+6+1
16
Therefore, that would equal 16.
The correct answer for this question is this one:
<span>On a piece of paper, use a protractor and a ruler to construct △ABC with AB=6 cm , m∠A=80° , and m∠B=50° .
What is AC ?
3 cm
<u>6 cm</u>
9 cm
12 cm</span>
If you try to draw the triangle, it forms an isosceles triangle.
side AB has a length of 6cm. Side AB = Side AC. So the length of Side AC is also 6 cm.
Hope this helps answer your question and have a nice day ahead.
