When we write x ⋅ x, or in simpler terms, x 2, we are multiplying two instances of x. The rule for exponents states that when multiplying terms with the same base, we add the exponents. For instance: x ⋅ x = x 1 + 1 = x 2. So, the distinction is important: x + x involves addition and therefore equals 2 x, while x ⋅ x involves ...
What happens if the gambler places a $2 bet on red in a single game of roulette? Because the random variable X represents a player’s profit from a $1 bet, the random variable 2 X represents the player’s profit from a $2 bet. The probability distribution of 2X is
How do you get X by itself? To get a variable by itself a combination of algebraic techniques is requiered. The distributive property, the addition and subtraction properties of equality to move all the terms containing x to one side of the equation, the multiplication and division properties of equality to eliminate any coefficients.
x + x is like terms, therefore x + x equal to 2x. x + x = 2x; FURTHER EXPLANATION. Algebra. A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe the constant changes in specific values in ...

The sum of x + x x+x x + x is 2 x 2x 2 x because we are adding the coefficients of each like term variable which are both 1. This is like saying: 1 x + 1 x = 2 x 1x+1x=2x 1 x + 1 x = 2 x. Another reason is that we can obtain x 2 x^2 x 2 if the operation is multiplication since x ⋅ x = x 2 x\cdot x=x^2 x ⋅ x = x 2 by rules of exponents (see ...

The statement "y is equal to 2x" is an example of a linear equation in two variables, x and y. This equation describes a straight line when graphed on a coordinate plane. Understanding the Equation. In the equation "y = 2x", the variable y is dependent on the value of x. The number 2 is the coefficient of x, which means that y is twice the ...
For p>2 and x∈ R , if the number of natural numbers in the range of f(x)=(x2 + 2 x + p/x2 + 2 x + 2) is 3, then the value of p is equal to Q. For p > 2 and x ∈ R , if the number of natural numbers in the range of f ( x ) = x 2 + 2 x + 2 x 2 + 2 x + p is 3 , then the value of p is equal to
