the second one;
the first one- 5*4=20--20+1=21 not 25
the second one- 7*2= 14--14+3=17
To determine which statement is true, we need to evaluate each expression and compare the results.
Let's first evaluate the expression 5x4+1. To do this, we need to perform the multiplication operation first, and then the addition operation.
5x4 = 20 (we multiply 5 and 4)
Once we have the result of the multiplication, we can add 1 to it:
20 + 1 = 21
Therefore, the expression 5x4+1 equals 21.
Next, let's evaluate the expression 3+7x2. In this case, we need to perform the multiplication operation first, and then the addition operation.
7x2 = 14 (we multiply 7 and 2)
Once we have the result of the multiplication, we can add 3 to it:
14 + 3 = 17
Therefore, the expression 3+7x2 equals 17.
Now, comparing the two statements:
- 5x4+1 = 21
- 3+7x2 = 17
We can see that the statement 5x4+1=25 is not true because the expression evaluates to 21. On the other hand, the statement 3+7x2=17 is true because the expression indeed evaluates to 17.
Therefore, the correct answer is: 3+7x2=17 is a true statement.
Depending upon where you put parentheses, which MUST be used for clarification, either can be correct.
5 x (4+1) = 25
3 + (7x2)=17
