Like I said you can't factor this. The GCD is 1 so you can't factor it. The GCD must be 2 or higher.

Answer:

(x - 1)(3x + 11)

Step-by-step explanation:

Given

3x² + 8x - 11

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 11 = - 33 and sum = + 8

The factors are - 3 and + 11

Use these factors to split the x- term

3x² - 3x + 11x - 11 ( factor the first/second and third/fourth terms )

= 3x(x - 1) + 11(x - 1) ← factor out (x - 1) from each term

= (x - 1)(3x + 11) ← in factored form

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

zaharov [31]

After 6 years the investment is $5555.88

Step-by-step explanation:

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

The formula used to find future value is:

$A(t)=P(1+\frac{r}{n})^{nt}$

where A(t) = Accumulated amount

P = Principal Amount

r = annual rate

t= time

n= compounding periods per year

We are given:

P = $3600

r = 7.5 %

t = 6

n = 1

Putting values in formula:

$A(t)=P(1+\frac{r}{n})^{nt}\\A(t)=3600(1+\frac{0.075}{1})^{6*1}\\A(t)=3600(\frac{1.075}{1})^6\\A(t)=3600(1.075)^6\\A(t)=3600(1.543)\\A(t)=5555.88$

So, After 6 years the investment is $5555.88

Assume that you ate 3/4 of a bag of popcorn and the person next to you ate 4/5 of a bag of popcorn.

AlekseyPX

Answer: The person next to you ate more popcorn.

Step-by-step explanation:

3 divided by 4 is 0.75, which is equivalent to 75%. 4 divided by 5 is 0.8, which is equivalent to 80%. Now that you've calculated the percentages of how much they ate, you can assume that 80 > 75 (80 is greater than 75).
