All literal equations have how many variables ?

more than one variable (two or more)

Explanation:

Literal equations are used to represent a known quantity/value using unknown values.

Now, if we have only one variable, then this variable will no longer be unknown as it will be equal to the known quantity. This means that the equation will not be literal.

Example:

Number of tickets is 25.

x = 25 where x is the number of tickets

If we have two variable, neither of them will be known. This means that the equation will be literal.

Example:

Number of apples added to number of bananas is 15.

x + y = 15

where x is the number of apples and y is the number of bananas, neither of them is known.

Based on the above, the literal equation must have more than one variable (two or more)

Hope this helps :)

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
