X^2+20=2x what are the values of x?

No real solutions.

Step.-by-step explanation:

Step 1: Subtract 2x from both sides.

For this equation: a=1, b=-2, c=20

Step 2: Use quadratic formula with a=1, b=-2, c=20.

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%
