Answer: 5(3x+5)

Step-by-step explanation:

To factor this expression we need to pull out the greatest common factor of the 2 numbers, 15 and 25. This factor is 5.

Now divide both numbers by 5 and put a 5 on the outside of the new expression to look like: 5(3x+5) and this is as far as it can be factored.

The Sommers invested $5000 for three years at 6.5%. How much interest did the investment earn in three years? What was the total
Jet001 [13]

Answer:

the interest is $975

the total amount  is $5975

Step-by-step explanation:

lets use tje formula

I=PRT

where I is interest earned

P is the principal amount(original amount)

R is the rate of interest

and T is the time in years

so

the principal amount is 5000 since it is the original amount

rate is \frac{6.5}{100}=0.065

time is 3 years

lets plug these values into our equation:

5000*0.065*3=I

5000*0.065*3=975

the interest is $975

the next part of the question is asking for the balance or the total amount which is principal+interest

5000+975=5975

the total amount or balance is $5975

hope this helps

PLEASE HELP ME GUYS :((​
Veseljchak [2.6K]

Answer:

8 - 8\sqrt{3}

Step-by-step explanation:

For this problem you have to use the 45-45-90 triangle theorem and 30-60-90 theorem.

For 45-45-90, the isosceles sides = 4, so the hypotenuse of the 30-60-90 triangle is 4 times 2, which is 8. If x is 8, then since y is the side across from the 60 angle, y is 8\sqrt{3. Since this really can't be simplified after y is subtracted from x, the final answer is just 8 - 8\sqrt{3}.
