Answer:
D: 18 x 10^12
Explanation:
Scientific notation is basically simplifying a huge number. So you have 18 and 12 0's. So its 18 x 10^12 (to the twelfth power)
<span>A countable quantitative variable that is finite is called a discrete variable while a non finite or infinite quantitative variable is known as a continuous variable. Discrete variables can only be a certain set of numbers while a continuous variable can be any number of values.</span>
The area of the rectangle is the product of its base and height
The height of the rectangle is 4x - 2 units
<h3>How to determine the height?</h3>
The given parameters are:
Area = 4x^2 - 2x
Base = x
The area of the rectangle is:
Area = Base * Height
This gives
4x^2 - 2x = x * Height
Divide through by x
4x - 2 = Height
Rewrite as:
Height = 4x - 2
Hence, the height of the rectangle is 4x - 2 units

F(x) = x^2 - 2x and g(x) = 6x + 4
(f + g)(x) = x^2 - 2x + 6x + 4 = x^2 + 4x + 4
(f + g)(x) = 0 => x^2 + 4x + 4 = 0
(x + 2)^2 = 0
x = -2
