Answer:
<h2>No, Sandra is not correct.</h2>
Step-by-step explanation:
Sandra was needed to multiply 438 by 17.
.
17 = 10 + 7.
Sandra multiplied 438 by 1 and then multiplied 438 by 7. Sandra had taken as the answer.
Multiplying by 1 and multiplying by 10 is not same.
Sandra mistakenly multiplied 438 by 1 instead of 10.
Hence, Sandra got the wrong answer.
