Answer:
w= -2
Step-by-step explanation:
3w + 2 = 8 + 6w
Subtract 3w from each side
3w-3w + 2 = 8 + 6w-3w
2 = 8+3w
Subtract 8 from each side
2-8 = 8-8+3w
-6 = 3w
Divide each side by 3
-6/3 = 3w/3
-2 =w
Answer:

Where "a" is the hypotenuse, and "b" and "c" are the legs of the right triangle.
Let be "c" the width of the television.
We can indentify in the figure that:

Then, we can substitute values and solve for "c":
