Ответ:
He wrongly distributed 9 over 15 and Y and got the wrong answer. The product of 9 and 15 is 135 not 90.
Step-by-step explanation:
Given the expression used by baker to show the number of muffins he needed to make as
, we are to check if the expression id equivalent to 90+Y
According to distributive law;
A(B+C) = AB + AC (This shows that A is distributed over B and C)
Applying distributive law on![9\left(15\:+\:Y\right)](/tpl/images/1004/9226/373ca.png)
From the result gotten, we can see that Emily is wrong because he wrongly distributed 9 over 15 and Y and got the wrong answer. The product of 9 and 15 is 135 not 90.
