Question

Solve for x and then find the length of 2x + 6 and 3x + 6.

Answer 1

Explanation:

1. 2x + 6 = 3x-6

2. 2x = 3x-12

3. -1x=-12

4. x=12

2(12) + 6 = 30

3(12) - 6 = 30

Answer 2

30

Explanation:

because S angle = T angle, this is isosceles triangle

=> SV=TV <=> 2x+6=3x+6

<=> x=12

=> SV=ST=30
