Note the equal sign. What you do to one side, you do to the other.
Also, remember to do the opposite of PEMDAS.
First, subtract 6 from both sides
-2x + 6 (-6) = -20 (-6)
-2x = -26
Next, isolate the x. Divide -2 from both sides
(-2x)/-2 = (-26)/-2
x = -26/-2
x = 13
13, or (B) is your answer

<em>~Rise Above the Ordinary, Senpai</em>
Answer:
15 ft
Basic fact:
<em>a square is a quadrilateral shape that has all sides of the same length and all the angles are the same</em>
Step-by-step explanation:
using the fact above, we know that there are 4 sides of the same length
to find the length of one side we have to do
60/4
=15
Sqrt(49)*sqrt (-1) -4 = 7i-4
your answer is
b = 15 pi
length of ypx = circumfrance of circle - 1/4 of circumfrance of circle
= 2pi r - 2pi r/4 = 6 pi r / 4 = 3 pi r / 2
= 3 pi × 10/2 = 15 pi
