Identify Parts of an Expression
Identify the variable(s)
3w+4
The quotient of 12 and u
12/u
Evaluate when r = 2
2r^3 - 4
12
Simplify by combining like terms:
5g +6y - 2g-y
3g+5y
Use substitution to evaluate if the expressions are equivalent:
3(2u+3)
2u + 4u+9
Equivalent!
A number next to a variable means what operation?:
Ex) 5g means .....
Multiplication

7 - 2 +b
Evaluate when x = 0 and y = 5
2x + 4y
20
Simplify by combining like terms:
13f^2 - f + 3f^2 +24f
16f^2 +23f
Use substitution to evaluate if the expressions are equivalent:
