3. A dish contains 100 candies. Juan removes candies from the dish each day and no
iVinArrow [24]

Answer:

11

Step-by-step explanation:

If i am correct n= the days so with the days adding up day 10 juan would have 55 of the 100 candies, day 11 he would have 66. The statement said at least 64, so it would have to be 64 or the closet amount to 64 but it cannot be lower than 64. So there for 66 is the closest to the given amount, and in order for juan to get 64 he would need to take candies out for 11 days.

a_sh-v [17]

Answer:

The answer to your question is (x + 3)

Step-by-step explanation:

                    \frac{5x + 5}{x} \frac{x^{3}+ 3x^{2}}{x^{2} - 1} \frac{x - 1}{5x}

Factor the expression

                   \frac{5(x + 1)}{x} \frac{x^{2}(x + 3)}{(x - 1)(x + 1)} \frac{x - 1}{5x}

Simplify

Cancel 5 because is in both numerator and denominator                  

Cancel (x + 1) because is in both numerator and denominator                  

Cancel (x - 1) because is in both numerator and denominator                  

Cancel x² because is in both numerator and denominator              

   

After simplifying, the result is  (x + 3)
