Please help me. what is the answer.

So first we need to substitute 3 into the expression
3^2 + 3 / 3 - 1
9 + 3 / 2
12 / 2 = 6
hope this helps! :)

6
If x=3 we first need to find the value of all the x’s is this equation starting with x to the power of two
3•3=9
now we add 3 to nine since it is directly next to it
3+9=12
for the divisor we have x-1
(3)-1=2
so now that we have all the values we simply divide
12/2=6

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
