The product of a binomial and a trinomial is x3+3x2-x+2x2+6x-2 Which expression is equivalent to this
solong [7]
The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2

What is the total amount for an investment of $1600 invested at 4.25% for 20 years and compounded continuously?
galina1969 [7]

Answer:

  $3743.43

Step-by-step explanation:

The amount is given by the formula ...

  A = Pe^(rt)

where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...

  A = $1600·e^(0.0425·20) = $1600·e^0.85

  ≈ $1600·2.33964685 ≈ $3743.43

The amount in the account will be $3743.43.

Explain why the equation 5z + 2 = 5z has no solution.
suter [353]
5z + 2 = 5z \\ 5z - 5z = - 2 \\ 0 = - 2

Answer : This is because when 5z minus 5z, it is nullified, with no way to determine the value of z. 5z - 5z = 0
That is why there is no solution for this equation.

Hope this helps. - M
