You need to remember your order of operations for this problem. Do what's inside the parentheses first to get 9 (7+2=9). Then the multiplication would be before the addition in the order of operations so 5 times 9 would be 45. Then add the 3. 45+3 is 48. The answer is 48.

3+5(7+2)
*First, what you do is use the distributive property and distribute the 5(outside parenthassees) to both the 7 and the 2
3+35+10
**Then you add them all together
35+3=38
38+10=48

always do any thing in the parentheses first, and then you do the multiplication.
3+5(7+2)=3+5(9)
3+(5x9)=3+45
3+45=48
and the answer is 48
