You would do 5 x 1= 5 and then add the three zeros
I^3 = i^(2+1) = i^2 x i -1 x i = -i
Solutions: x=1<span>. Hope its right :)</span>
Set it up like a regular equation. I used:

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u>

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.
Answer:
it would help if we could see it
