5 + 84 Numerical 3x + 10 Algebraic Expressions An expression is NOT an equation because it DOES NOT have an equal sign. There are 2 types of expressions. 5 + 84 Numerical 3x + 10 Algebraic Notice there are no equal signs in these expressions so they are not equations!
For each phrase below, pick variables to represent the unknowns. State what the variables represent, and then write the phrase as an algebraic expression in one variable. Example: The longest side of a triangle is twice the length of the shortest; ...
On adding a monomial ……… to -2x+4y2+z, the resulting expression becomes a binomial. Solution: We can add 2x, -4y2and -z to the expression to make it binomial. => 2x + (-2x + 4y2+ z) = 4y2+ z => -4y2+ (-2x + 4y2+ z) = -2x + z => -z...
