Triangle ABC is shown on the grid. A(-1, 5) B(4, 5) C (-1, 1) What is the perimeter of triangle ABC? 9 + sqrt 21, 9 + sqrt 29, 9 + sqrt 41, 9 + sqrt 61

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

6-3*t-(15)=0

Step by step solution :

Equations which are never true

Solve : -3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

Solve : t+3 = 0

Subtract 3 from both sides of the equation :

t = -3

One solution was found :

t = -3
