Its an isosceles triangle and just for future reference, you can google the types of triangles and you will find websites with definition and answers
Answer:
The solution to the equation is:
- <u>x = 2.5</u> or <u>x = 5/2</u>
Step-by-step explanation:
To find the solution to the equation, you only must operate the equation until you clear the x variable, with the next steps:
And we solve:
- 4x + 28 = 38 (we multiply 4 by x and 7)
- 4x = 38 - 28 (we pass the +28 to subtract to the right side of the equality and operate)
- x = 10 / 4 (we pass the 4 that is multiplying to divide to the right side of the equality)
- <u>x = 2.5</u> (we divide)
As you can see, <u><em>the solution of the equation is </em></u><u><em>x = 2.5</em></u><u><em> or </em></u><u><em>x = 5/2</em></u>
