H(x) = 3x2 - 2x + 13<br> h(3)<br> [?]
kow [346]

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.
