Hey there! I'm happy to help!
Since this mural is a square, all the sides are the same. This means that you square on of the sides to get the area (multiply it by itself). If we have the area and want to find a side, we just go backwards and use something called the square root!
If we plug this into our calculators...
√138≈11.74734
We see that is closest to B. 12 ft.
You could also figure this out without a calculator. 138 is very close to 144, which is 12². All the other answer options are way too big.
Have a wonderful day! :D
100 thousands is the answer good luck!

Solve the following equation:
![\left[\begin{array}{ccc}3&2\\5&5\\\end{array}\right] \left[\begin{array}{ccc}x_{1}\\x_{2}\\\end{array}\right] + \left[\begin{array}{ccc}1\\2\\\end{array}\right] = \left[\begin{array}{ccc}2\\-3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%262%5C%5C5%265%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx_%7B1%7D%5C%5Cx_%7B2%7D%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%2B%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%5C%5C2%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%5C%5C-3%5C%5C%5Cend%7Barray%7D%5Cright%5D)
-In order to solve a pair of equations by using substitution, you first need to solve one of the equations for one of variables and then you would substitute the result for that variable in the other equation:
-First equation:
-Second equation:
-Choose one of the two following equations, which I choose the first one, then you solve for 
by isolating
-Subtract 
to both sides:
-Subtract 
to both sides:
-Divide both sides by 
:
-Multiply 
by 
:
-Substitute 
for in the second equation, which is :
Multiply by 
:
-Combine like terms:
-Subtract 
to both sides:
-Multiply both sides by 
:
-After you have the value of 
, substitute for 
onto this equation, which is :
-Multiply 
and 
:
-Since both and 
have the same denominator, then add the numerators together. Also, after you have added both numerators together, reduce the fraction to the lowest term:
