Answer:
25
Step-by-step explanation:
When you substitute x for 3, the new equation would be ; 3(3)(2) - 2(3) + 13
using order of operations from left to right, you would start by multiplying
3(3)(2) and 3(3) is 9, and 9(2) is 18. The next step is to multiply 2 and 3 which is 6. Once you have both groups of numbers simplified, you can plug them back in : 18 - 6 + 13 ; 18 - 6 is 12, and 12 + 13 is 25, so the answer is 25.
