First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4

Suppose a triangle has 3 sides, 3, 4, 6 which of the following must be true
Inessa [10]

Answer:

  B. the triangle in question is not a right triangle

Step-by-step explanation:

___

3, 4, 5 is one of the first Pythagorean triples that you learn:

  3² + 4² = 5²

These are the side lengths of the smallest right triangle with integer sides. It is worthwhile to remember. This triple is used not only in many math problems (such as this one), but also in real life when it is useful to lay out a right angle.
