Answer:

x = 4

Step-by-step explanation:

Since it's a equilateral triangle, all sides are equal

So you can do the equation 3x - 1 = 11

You then add 1 on both sides, leaving the equation as 3x = 12

You divide both sides by 3, which leaves you with x = 4

What is the circumference of the circle that circumscribes a triangle with side lengths 3, 4, and 5?
djyliett [7]

Answer:

  5π, about 15.708 units

Step-by-step explanation:

A 3-4-5 triangle is a right triangle. When a circle circumscribes a right triangle, the hypotenuse is the diameter of the circle. The circumference of a circle is given by ...

  C = πd

For a diameter of 5 units, the circumference is ...

  C = π(5) = 5π = 15.708 . . . units

_____

<em>Additional comment</em>

The (3, 4, 5) triple is one of the first Pythagorean triples you run across. It is the smallest integer triple, and the only primitive triple with values in an arithmetic sequence. You can show this is a Pythagorean triple by ...

 3² + 4² = 9 +16 = 25 = 5²

That is, these numbers satisfy the Pythagorean theorem relation for sides of a right triangle.

2b + 8 − 5b + 3 = -13 + 8b − 5<br><br><br><br> b = __
Bumek [7]

Answer:

b= 29/11

Step-by-step explanation:

2b+8−5b+3=−13+8b−5

Step 1: Simplify both sides of the equation.

2b+8−5b+3=−13+8b−5

2b+8+−5b+3=−13+8b+−5

(2b+−5b)+(8+3)=(8b)+(−13+−5)(Combine Like Terms)

−3b+11=8b+−18

−3b+11=8b−18

Step 2: Subtract 8b from both sides.

−3b+11−8b=8b−18−8b

−11b+11=−18

Step 3: Subtract 11 from both sides.

−11b+11−11=−18−11

−11b=−29

Step 4: Divide both sides by -11.

−11b/−11 = −29/−11

b= 29/11
