Answer:

18 inches.

Step-by-step explanation:

We are asked to find the perimeter of an equilateral triangle with a side of 6 inches.

We know that perimeter of a triangle is equal to sum of length of three sides.

We also know that all sides of equilateral triangle are equal, so perimeter of our given triangle would be $3\times 6\text{ inches}=18\text{ inches}$ .

Therefore, the perimeter of the given triangle is 18 inches.

Answer:

The constant of proportionality is thus 1

Step-by-step explanation:

Note that the green line passes through (6, 6) and has a y-intercept of 0. Thus, the equation of the line is y = (6/6)x + 0, or y = x, or y = 1x.

The constant of proportionality is thus 1, which is also the slope of this line.

<h3>Answer:</h3>

2.25

<h3>Explanation:</h3>

Consider the square ...

... (x+a)² = x² +2ax +a²

The constant term (a²) is the square of half the x-coefficient: a² = (2a/2)².

The x-coefficient in your expression is 3. The square of half that is ...

... (3/2)² = 9/4 = 2.25

Adding 2.25 to both sides gives ...

... x² +3x + 2.25 = 6 + 2.25

... (x +1.5)² = 8.25 . . . . completed square

timofeeve [1]

Answer:

The answer is 256 $in^{3}$ .

Step-by-step explanation:

To solve for the volume of the sphere, start by using the sphere volume formula, which is V = $\frac{4}{3} \pi r^{3}$ . However, in this formula, 3 will be used instead of ( $\pi$ ).
