Combine like terms on the left side of the equation. Add 4 and 2 and subtract x and 2x. After combining like terms you should get: 6 - x = 5.
Subtract 6 from both sides to isolate x. Now you have: -x = -1. Make x into a positive by dividing both sides by -1. You are correct - the answer is x = 1.
Isosceles - Has at least two equal sides. (B)
Obtuse Triangle - Must have an obtuse angle. (D)
Equilateral Triangle - All sides should be equal. (Missing an answer?)
Right Triangle -Must include a 90 degree angle. (A)
Scalene Triangle - Has NO equal sides. (C)

<span>Use the Pythagorean Theorem to solve. This will be a right triangle:
=
Let the slope = the hypotenuse = c
Let one side = a=8
Let the other side =b =15
Plug-in the values and solve for the c-term
Check you answer by plugging the value of "c" back into the orignial equation and solve.
