Question

Mya applied the distributive property to write the equivalent expressions below

45+ 72 - 9(5 + 9)
What is Mya's error?
Mya did not write the common factor in the correct place,
Mya wrote two expressions that are not equivalent
O Mya did not use the correct operations in the equation,
Mya used a factor that is not common to 45 and 72,

Answer 1

Mya wrote two expressions that are not equivalent

Explanation:

45 +72 does not equal to 9(5+9)

9(5+9) = 45 + 81

Answer 2

D

Explanation:

I dislike these kinds of questions. I could argue either of 2 answers - b and d.

b says that her error was that she wrote two expressions that are not equivalent and that is true. She did not write equivalent expressions.

d says she didn't use a common factor to both terms and that is true.

The actual answer is that she made a silly error which we all often do.

8 * 9 is 72

so the distributive property should be

9(5 + 8)

So, what's the answer? I would pick D, but hold your nose when you enter it.
