No, this triangle is not equilateral. This triangle is scalene. All three sides are of different lengths, which is why it's scalene. In order to have an equilateral triangle, all three sides need to be the same length.

morpeh [17]

Answer:

The answer is "d \neq 3c,f and g are arbitrary".

Step-by-step explanation:

The matrix of the device is increased  

\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right]

Reduce the echelon row matrix  

\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right] \\\\R_1 \leftrightarrow  R_2 \\\\\frac{R_2 -1}{C R_1 \to R_2}   \sim   \left[\begin{array}{ccc} c&d&g\\ 0 & \frac{3c-d}{c}& \frac{cf-g}{c}\\ \end{array}\right]

Therefore, if 3c\neq 0 is d \neq  3c, the device is valid.  Therefore d \neq are arbitrary 3c, g and f.
