An equation in the variable n.
It is either 3*2 + a or 3*(2 + a)
The variable in 14x is x.
It is not a variable. The equation says that the energy contained in any given mass is equivalent to the mass times the velocity of light squared.
The variable c times the variable b simply equals cb. Just as the variable x times the variable y would equal xy, and so on.
A variable times the same variable is called a square of that variable. For example, if the variable is x, then x multiplied by x is written as x^2, which is read as "x squared."
a2/2
An equation in the variable n.
x=2 and y=3
It is either 3*2 + a or 3*(2 + a)
The variable in 14x is x.
It means that you multiply 2 by any given number (h) and then multiply by 5. h is the variable. A variable is anunknown number. So if h is 3, then you replace it with h so 2 times 3 is 6 times 5 is 30.
It is not a variable. The equation says that the energy contained in any given mass is equivalent to the mass times the velocity of light squared.
The variable c times the variable b simply equals cb. Just as the variable x times the variable y would equal xy, and so on.
"Wat" is the variable.
If a variable has possible values -2 6 and 17 then this variable is an Integer.
When you see "y times 2," it means you are multiplying the variable y by the number 2. So the expression "y times 2" can be written as 2y. This is a simple algebraic expression where the coefficient of y is 2.
