The expression -2 3x can be represented as "negative two times three times a variable x" or "negative two multiplied by three times x." The expression 3x - 2 can be phrased as "three times a variable x minus two." Both expressions involve multiplication and subtraction of the variable x with constants.
An equation in the variable n.
The algebraic expression for 5 times a plus 6 times a squared can be written as (5a + 6a^2). In this expression, (5a) represents 5 times the variable (a), and (6a^2) represents 6 times the variable (a) squared.
It is either 3*2 + a or 3*(2 + a)
The expression (3t \times 3t) can be simplified by multiplying the coefficients and the variable separately. First, multiply the coefficients: (3 \times 3 = 9). Then, multiply the variable (t) by itself: (t \times t = t^2). Therefore, the result is (9t^2).
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."

The expression -2 3x can be represented as "negative two times three times a variable x" or "negative two multiplied by three times x." The expression 3x - 2 can be phrased as "three times a variable x minus two." Both expressions involve multiplication and subtraction of the variable x with constants.
An equation in the variable n.
x=2 and y=3
It is either 3*2 + a or 3*(2 + a)
The expression (3t \times 3t) can be simplified by multiplying the coefficients and the variable separately. First, multiply the coefficients: (3 \times 3 = 9). Then, multiply the variable (t) by itself: (t \times t = t^2). Therefore, the result is (9t^2).
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.
