RT = RS + ST
8x - 43 = 2x - 4 + 4x - 1
8x - 43 = 6x - 5
8x - 6x = -5 + 43
2x = 38
x = 38/2
x = 19
QS = 2RS = 2(2x-4) = 2(2*19-4) = 2*34 = 68
|-13+2| is 11 and |10+1| is 11, so yes they are equal
Answer:
Option 2 would be the best answer
Step-by-step explanation:

In this case, a= 3x and b= 4
Since there is a power 2, it is a quadratic equation not a linear equation.
