What is an Expression?
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
To know the expressions that are equivalent to 22c+33d, all the expressions in the options are needed to be simplified.
Let simplify each of the given opion,
A.) (−2c−3d)(−11) = 22c + 33d
B.) 2(11c− 33/2) d = 22c - 33d
C.) (66c+99d)⋅1/3 = 22c + 33d
D.) −1×(−22−33d) = 22 + 33d
E.) 11⋅(2c+3d) = 22c + 33d
Hence, the correct options are A, C, and E.
The complete question is:
Which expressions are equivalent to 22c + 33d?
