Greeting!

15x² = x + 2
15x² - x -2= 0
Factor left side
(5x-2)(3x+1)=0
Set factors equal to 0
5x - 2 = 0 or 3x + 1 -0
x = 2/5 or x= -1/3

I hope that helps!

$394.51 is future value of money after 2 years.

What future value means?

  • A current asset's future value (FV), which is based on an estimated rate of growth, is its value at a later time.
  • Investors and financial planners use the future value to project how much an investment made now will be worth in the future.

The method that results in more money after 2 years is Peggy's investment.

Which method results in more money in 2 years?

The formula for calculating the future value of an investment:

FV = P (1 + r)^nm

FV = Future value

P = Present value

R = interest rate

m = number of compounding

N = number of years

Future value of Larry's investment: $350 x [1 + (0.04/4)]^(4 x 2) = $379

Future value of Peggy's investment: $350 x [1 + (0.06/12)]^(12 x 2) = $394.51

Tresset [83]

Answer: A.) 10x + 15

Step-by-step explanation:

You would distribute (multiply) the 5 to the 2x which would then make it 10x and you would distribute (multiply) the 5 to the 3 which would then make it 15. Because the 5 is a positive number the sign stays the same.

Therefore, 10x + 15 is your answer.

In circle S with mZRST = 86 and RS = 4 units find area of sector RST. Round to
Andru [333]

Answer:

Area = 12.00

Step-by-step explanation:

Given

\theta = m\angle RST = 86^o

r = RS = 4

Required

Area of RST

The sector area is calculated using:

Area = \frac{\theta}{360} * \pi r^2

So, we have:

Area = \frac{86}{360} * 3.14 *4^2

Area = \frac{86* 3.14 *4^2}{360}

Area = \frac{4320.64}{360}

Area = 12.00 ------------ approximated
