Quick due today from a square cardboard sheet, a 3 cm wide strip was cut away. the area of the remaining rectangular cardboard sheet is 70 cm². find the original dimensions of the square cardboard sheet.

The original dimensions of the square cardboard are 10cm and 7cm.

Let the original dimensions of the square cardboard be represented by x.

Based on the information given in the question, the equation to solve the question will be:

(x)(x - 3) = 70

x² - 3x = 70

Collect like terms

x² - 3x - 70 = 0

x² - 10x + 7x - 70 = 0

x(x - 10) + 7(x - 10)

x - 10 = 0

x = 0 + 10 = 10

Therefore, the original dimensions of the square cardboard are 10cm and 7cm.

the answer is b.)

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%
