2(2x^2-3) -5
4x^2 - 6 - 5
4x^2 - 11
g(x) = 2x - 5
If you had to evaluate g(3)
You would substitute 3 in for the x and simplify. Instead of substituting a single number you are substituting the binomial
2x^2 -3 and then simplifying. I hope you understand.
Answer:
c- Division property of equality
Step-by-step explanation:
You would subtract 7x from the other side
Then divide by 8 to get x by itself.
Mixing is a physical reaction, which does not change any chemical properties of elements and molecules because it does not change the number of protons.
It is the number of protons that determine the unique properties of each element (hence why the periodic table sorts elements by increasing the number of protons).
Well
3x^2+6x-x-2
So the answer would be
3x^2+5x-2
