Answer:

Only 6

Step-by-step explanation:

We need to factor the equation to find the solution. TO factor we need to find what times what = 36, and what plus what equals -12.

-6 times -6 = 36

and -6 + -6 = -12

So this can be factored into

(x-6)(x-6)=0

We can find the solution by setting each parentheses equal to zero.

x-6 = 0

x = 6

So the only solution is 6

I attached an image that shows an example of factoring.

Harrizon [31]

Total number of hours she schduled to play the game = 3 $\frac{3}{4}$ hours.

Let us convert mixed fraction into improper fraction

$3\frac{3}{4} = \frac{3*3+4}{4} = \frac{13}{4} \ hours.$

Duration of each round = $\frac{7}{12}$ .

In order to find the number of rounds Nicole can play, we need to divide total number of hours by duration of each round.

$\frac{13}{4}$ ÷ $\frac{7}{12}$

Converting division sign into multiplication flips the second fraction.

$=\frac{13}{4} \times \frac{12}{7}$

Crossing out 12 by 4, we get 3 on the top of second fraction.

$=\frac{13}{1} \times \frac{3}{7}$

$=\frac{39}{7} = 5.57...( Approximately).$

Because problem is about number of rounds.

So, total number of round would be 5.

Holly wants to save money for an emergency. Holly invests 1,500 in an account that pays an interest rate of 6.75%. How many year

lina2011 [118]

The formula is
A=p (1+r)^t
A future value 7300
P present value 1500
R interest rate 0.0675
T time?
7300=1500 (1+0.0675)^t
Solve for t
Divide both sides by 1500
7300/1500=1.0675^t
Take the log for both sides
Log (7300/1500)=t×log (1.0675)
Divide both sides by log (1.0675)
T=log(7,300÷1,500)÷log(1.0675)
T=24.2 years round your answer to get 24 years

Hope it helps!
