3x - 4 + x^2 - 1 + 2x^2 - 15
3x^2 + 3x - 20
I wasn't sure if you wanted me to solve for x, but I did anyways.
x ≈ 1.86, or -2.86
It would be associative property because the order of the numbers stayed the same
She would have saved 30 dollars.
Is this 9x+4=5+5x or is it 9x•4=5•5x?
The pattern is dividing by 2 every time so the next 3 numbers will be 1/8, 1/16, 1/32
