QuestionWhich of the formulas below are valid? Select all that apply? a. $=J 5+C 21 / D 21$ b. $=A+B+C$ c. $=1-3$ d. $\mathrm{C8}+\mathrm{C7}$

Studdy Solution
Determine if the formula uses valid cell references and operators:
a. $=J5+C21/D21$ - Uses valid cell references and operators. b. $=A+B+C$ - Uses valid cell references and operators. c. $=1-3$ - Uses valid numbers and operator.
The valid formulas are: - a. $=J5+C21/D21$ - b. $=A+B+C$ - c. $=1-3$
