Answer:
x^2 -6x +6
Step-by-step explanation:
<em>Square of a difference (can be found in IM2)</em>
Formula: a^2 -2ab +b^2
x= a; 3= b
(x -3)(x -3)
<em>Plug in to formula.</em>
x^2 -2(x)(3) +3^2
<em>Simplify.</em>
x^2 -6x +6
Answer:
Hello my friend! The first step is to isolate the x and the 40 like this: x2 = 40.
Step-by-step explanation:
After you do that, you can perform the inverse operation of the x2, wich is the sqrt of 40. This way, you will have x=sqrt40 . X~=6.32

Answer:
138
Step-by-step explanation:
x is an exterior angle of a triangle.
If you didn't know, an exterior angle of a triangle is equal to the sum of its opposite interior angles.
The opposite interior angles of x have measures of 80 degrees and 58 degrees.
Hence, x = 80 + 58 = 138
Answer:
<h2>(5,4)</h2>
Step-by-step explanation:
Let us all know that in order to find the midpoint of a segment we can use the midpoint formula
(x1+x2/2, y1+y2/2)
now let us put in the values into the formula
(-2+12/2, 18-10/2)
now lets simplify
(10/2, 8/2)
(5,4)
I hope this helped you :)
