Ответ:
(300-28)7
Step-by-step explanation:
You always do parenthesis first and then the 7 means to do multiplication if it is right next to the parenthesis
Ответ:
Work out parenthesis.
Collect terms
Now we can see that both sides of the equation are exactly the same. Therefore, it doesn't matter whatever value of x you plug into the equation. Each value of x you plug into the equation makes the equation correct, because both sides are the same (both sides have the same outcome value).
The answer is A.
