Add the following polynomials. Write your final answer only on the space provided. In writing the exponent just write it after the variable or use the symbol ^.

Ex. 3x2 write is as 3x2 or 3x^2

1. (2m - 8n + 6) + (4n - 3) =

2. (4y2 - 3xy + x2) + (y2 + 3xy + 3x2) =

3. (8x + 7) + (2x - 6) =

4. (n + 5) + (2n + 7) =

5. (2a + 8) + (a + 2) =

6. (4m + 3n - p) + (2p - 3n + 2m) =

7. (5x2 - 3x + 6) + (x2 + 5x - 15) =

8. (3d - 4e + 6) + (2d +5e + 1) =

9. (5x - 3y) + (10y - 4z) + (2x - 3z) =

10. (2a + 3) + (a - 9) =

Step-by-step explanation:

1. (2m - 8n + 6) + (4n - 3) =  2m - 4n +3

2. (4y2 - 3xy + x2) + (y2 + 3xy + 3x2) =  4 -  6xy + 4x2

3. (8x + 7) + (2x - 6) = 10x + 1

4. (n + 5) + (2n + 7) =  3n + 12 which can also be written as common factor;  3(n +4).

5. (2a + 8) + (a + 2) =  3a + 10

6. (4m + 3n - p) + (2p - 3n + 2m) =  6m + p

7. (5x2 - 3x + 6) + (x2 + 5x - 15) =  6x^2 + 2x - 9

8. (3d - 4e + 6) + (2d +5e + 1) =  d - e + 6

9. (5x - 3y) + (10y - 4z) + (2x - 3z) = 7x + 7y - 7z

10. (2a + 3) + (a - 9) = 3a - 6,  common factor 3 (a-2)



answer: 25 is the correct answer

step-by-step explanation:

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
