The answer is x(x-8)(x+8)
Here is the process;
x^3-64x
x(x^2-64)
You know that it will be a x- and a x+ becuase there is no middle x value
x(x-)(x+)
x(x-8)(x+8)

You find a deck of cards and know that the deck has too many clubs and spades in it. The deck has 59 cards.

Harrizon [31]

(13/59)(c/58)=117/1711

13c/3422=117/1711

13c=234

c=18

So there are 18 clubs instead of 13 meaning that there is an extra 5 clubs in the deck.

Since there were 59 cards, there was 7 extra cards in all. The 7 extra minus the 5 extra clubs leaves 2 extra spaces.

So there were two extra spades in the deck.

A survey showed that 9 every 25 students like dogs while 13th of every 20 students like cats. How many more of the students like

lilavasa [31]

Answer:

29/100 (Every 100 students, 29 more students like cats than dogs)

Step-by-step explanation:

First we need to put these numbers in fractions

The fraction that represents students that like dogs is 9/25

The fraction that represents students that like cats is 13/20

Now, we just need to subtract the fraction of cats by the fraction of dogs:

13/20 - 9/25

To do that, we need to make the denominators equal. We do that making multiplying the first fraction by 5 and the second by 4, so we have:

13/20 = 65/100

9/25 = 36/100

Then, subtracting then, we have:

65/100 - 36/100 = 29/100

So every 100 students, 29 more students like cats than dogs.

You need to buy a car to help you get to school and work. You take out a $8,000 loan with a 9.25% annual simple interest rate to

vovikov84 [41]

Answer:

A) Interest that will be charged = $4070

B) The total amount to be paid = $12070

Step-by-step explanation:

Given:

Initial amount paid = $8,000

Rate of the interest = 9.25%

Time period = 66 months

A) AMOUNT OF INTEREST CHARGED

Let the interest charge be x

$\text{Simple interest, x} =\frac{\text { principal amount } \times \text {rate of interest } \times \text { number of years }}{100}$

here we are given with number of months i.e., 66 months

converting 66 months into years

=> $\frac{66}{12}$

=>5.5

so 66 months = 5.5 years

Now substituting the vales in the formula we get,

simple interest, x = $\frac { 8000\times 9.25 \times5.5}{100}$

simple interest, x = $\frac {74000 \times5.5}{100}$

simple interest, x = $\frac {407000}{100}$

simple interest, x = 4070

B) TOTAL AMOUNT TO BE PAID:

Let the total amount paid after 66 months be Y

Then ,

Y = Principal amount + interest for 66 months

Y = 8000+ 4070

Y =12070
