\bf \cfrac{x}{x-2}+\cfrac{x-1}{x+1}=-1\impliedby LCD\to (x-2)(x+1)\\\\
-------------------------------\\\\
\cfrac{x(x+1)+(x-1)(x-2)}{(x-2)(x+1)}=-1
\\\\\\
x^2+x+x^2-3x+2=-1(x-2)(x+1)
\\\\\\
2x^2-2x+2=-1(x^2-x-2)\implies 2x^2-2x+2=-x^2+x+2
\\\\\\
3x^2-3x=0\implies 3x(x-1)=0\implies 
\begin{cases}
3x=0\implies &x=0\\
x-1=0\implies &x=1
\end{cases}

3. What is the exact area of triangle ABC? Use special right triangles to help find the base of the triangle. Show your work.
Oduvanchick [21]

The exact area of triangle ABC is 93.51 cm².

The given parameters;

  • <em>Height of the triangle, h = 18 cm</em>

The base of the triangle is calculated by using trigonometry ratio as follows;

tan (30) = \frac{b}{18} \\\\

where;

  • <em>b </em><em>is the </em><em>base </em><em>of the </em><em>triangle ABC</em>

<em></em>

<em></em>b = 18 \times tan(30)\\\\b = 10.39 \ cm<em></em>

The area of the triangle ABC  with the calculated base and given height is calculated as follows;

A = \frac{1}{2} \times base \times height\\\\A = \frac{1}{2} \times 10.39 \times 18\\\\A = 93.51 \ cm^2

Thus, the exact area of triangle ABC is 93.51 cm².

May anyone give me an example of a independent and an dependent probability word problem about food?
Rufina [12.5K]
Dependent: Ventus has a bag of chex mix and he spent his time counting and organizing the food. There are 13/31 white pieces of chex, 10/31 pretzels, and 8/31 cracker bites.  he wants to see if he can grab two white chex pieces, one at a time without replacing the first attempt. He reaches his hand into the bag and gets a white chex piece and doesn't replace it. What is the probability that Ventus will grab another white chex?
 independent: Cabel has a bowl of fruit and his sister won't let him take one and look at it for some strange reason/ however, she does tell him the probability of picking each fruit out of 12. 2/6 oranges, 3/12 apples, and 5/12 bananas. He must replace every fruit he picks. What is the probability of picking an orange?
