--First we have to simplfy

\frac{2x-8}{x^2-x-12} -\frac{x-3}{x(x+1)}

\frac{2(x-4)}{(x-4)(x+3)} - \frac{x-3}{x(x+1)}

--Cancel common factors

\frac{2}{(x+3)} -\frac{x-3}{x(x+1)}

--Here remember never cancel factors in a subtraction or addition problem

--Now Multiply each side until both denominators are equal to each other

\frac{2[x(x+1)]}{x(x+3)(x+1)} -\frac{(x-3)(x+3)}{x(x+3)(x+1)}

--Simplify

\frac{2x^2+2x}{x(x+1)(x+3)} - \frac{x^2-9}{x(x+1)(x+3)}

--Now that the denominators are the same: subtract!

\frac{2x^2+2x-(x^2-9)}{x(x+1)(x+3)}

\frac{2x^2-x^2+2x+9}{x(x+1)(x+3)}

--And LAST STEP! ......Simplify More.... To get your answer

\frac{x^2+2x+9}{x(x+1)(x+3)}

Step-by-step explanation:

You deposit $2700 into a bank account paying 64.8% simple interest per year. You left the money in for 1 year. Find the interest earned and the amount at the end of those 1 year?

Result:

The interest is $1749.6 and the amount is $4449.6.

Explanation:

STEP 1: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this examplee P = $2700, i = 64.8% and t = 1 years, so

 

STEP 2: Find an amount by using the formula .A =P+I

Since P = $2700 and I = $1749.6 we have

In a standard deck of cards there 52 cards of which 26 are black and 26 are red. Additionally, there are 4 suits, hearts, clubs,
stich3 [128]

Using probability concepts, it is found that P(S and D) = 0.1275.

-----------------------

  • A probability is the <u>number of desired outcomes divided by the number of desired outcomes</u>.
  • In a standard deck, there are 52 cards.
  • Of those, 13 are spades, and 13 are diamond.

  • The probability of selecting a spade with the first card is 13/52. Then, there is a 13/51 probability of selecting a diamond with the second. The same is valid for diamond then space, which means that the probability is multiplied by 2. Thus, the desired probability is:

P(S \cap D) = 2 \times \frac{13}{52} \times \frac{13}{51} = \frac{2\times 13 \times 13}{52 \times 51} = 0.1275

Thus, P(S and D) = 0.1275.
