The <span>Triangle Inequality Theorem establishes that the length of the triangle is shorter than the sum of the two lenghts of the others two sides. Then, you have:
a=6 (the lenght of a side of the triangle).
b=13 (t</span>he lenght of a side of the triangle).<span>
c=x (the length of the third side).
Therefore:
c<a+b
c<6+13
c<19
The lenght of the third side is:
(13-6)<c<19
7<c<9</span>
Answer:
10
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Simplifying
2y + -6 = 12
Reorder the terms:
-6 + 2y = 12
Solving
-6 + 2y = 12
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 2y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 2y = 12 + 6
2y = 12 + 6
Combine like terms: 12 + 6 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
