Answer:

Perimeter of triangle is 38 inches

Step-by-step explanation:

Figure show triangle with sides of (21-x), (2x-3)and(x+5)

Here, The pool balls are arranged in triangle in symmetry.

Hence, Triangle is equilateral triangle.

For equilateral triangle,

Sides are equal in length (21-x) = (2x-3) = (x+5)

Take (2x-3) = (x+5)

2x-3=x+5

2x-x=5+3

x=8.

Now,Perimeter of triangle is summation of all of the sides.

= (21-x) + (2x-3) + (x+5)

= (21-8) + (2(8)-3) + (8+5)

= 13 + (16-3) +12

= 13+13+12

= 26+12

= 38 inches

How do you do this question?

daser333 [38]

Answer:

B. 1/2

Step-by-step explanation:

$\lim_{z \to 0} \frac{g(z)e^{-z}-3}{z^{2}-2z}$

If we plug in 0 for z, we get 0/0. Apply l'Hopital's rule.

$\lim_{z \to 0} \frac{-g(z)e^{-z}+g'(z)e^{-z}}{2z-2}$

Now when we plug in 0 for z, we get:

$\frac{-g(0)e^{0}+g'(0)e^{0}}{2(0)-2}\\\frac{-g(0)+g'(0)}{-2}\\\frac{-3+2}{-2}\\\frac{1}{2}$
