Question

Hi i really need help w this

Answer 1

6x=4x+8, 6x-4x-8=0, 2x-8=0, 2x=8, x=8/2=4

Explanation:

As we see from the ticks the all sides of the triangle are equal. Therefore 6x=4x+8=3x+12. And from these we got answer.

Answer 2

Answer: x = 4

Explanation:

The given triangle has a stroke on each of its three sides. Each stroke is a an indication that the three sides are equal. It means that the triangle is an equilateral triangle. Therefore,

4x + 8 = 6x = 3x + 12

4x + 8 = 6x

Subtracting 4x from the left hand side and the right hand side of the equation, it becomes

4x - 4x + 8 = 6x - 4x

6x - 4x = 8

2x = 8

Dividing the left hand side and the right hand side of the equation, it becomes

2x/2 = 8/2

x = 4
