Question

Valerie used the distributive property to write an equivalent expression.

What is Valerie's error?
12 + 32 = 4(1 + 10)
O Valerie wrote two expressions that are not equivalent.
O Valerie used the factor 4, which is not common to 12 and 32.
Valerie did not divide each addend by the GCF to get (1 + 10).
. Valerie did not use the correct operations in the equivalent expression.

Answer 1

She did no divide each addend correctly

Explanation:

Given

12 + 32 ← factor out 4 from each addend

As 4 × 3 = 12 and 4× 8 = 32

Valerie had 12 + 32 = 4(1 + 10) ← incorrect statement
