<u>formula: </u>
(a+b)^2
= a^2+2ab+b^2
Here, we have x^2 (as in a^2)
and -6x (as in 2ab), which, we're missing the b^2
(I'm not really sure how to describe this but bare with me)
-6/2 (-6 is from the -6x) = -3 (the b)
-3^2 = -3*-3 which is equal to 9 (positive 9)
Writing it out -
x^2-6x+9 = -5
- Addition of inequality -
Since we add 9 to the left side, we have to add 9 to the right side; which gives us:
x^2-6x+9=4
Next, lets put the x^2-6x+9 as in (a+b)^2:
(x-3)^2 = 4
<em>Then let's do the square root of equality (square rooting both sides) :</em>
<u>x-3 = 2</u>
<em>Finally lets add 3 to both sides</em>
<u>x = 5</u>
THE ANSWER IS <u><em>x=5</em></u>

Answer:
Depending on your math class, possibly: "I will complete at least 10 math problems by the end of class today."
Step-by-step explanation:
a SMART goal is Specific, Measurable, Attainable, Relevant, and Time-based. The goal has a time frame to make it easy to accomplish.
The area of any regular polygon can be expressed as:
a(n,s)=(ns^2)/(4tan(180/n)), where n=number of sides and s=side length
(notice apothem is not needed :P)
a(6,5)=(6*5^2)/(4tan(180/6)
a(6,5)=37.5/tan30
a(6,5)≈64.95 units (to nearest hundredth of a unit)
