The length is 4.22 inches. The first time you press the button, the copy becomes 1-12%=88% of its original length. When you press it again, it becomes 88%*88% of its original length. By the same reasoning, if you press it for 5 times, the final length is 8*(88%)^5=4.22 inches rounded to the nearest hundredth.
Answer: x^2 -3
That's x squared minus three
Step-by-step explanation:
When you divide 2x^3 by 2x the 2's cancel, and x cubed becomes x squared.
In 6x divided by 2x, the X's cancel and 6 ÷2=3
BTW "cancels" means that a number divided by itself equals one, so it "disappears" from the expression
7, 0, -2. i think this is right
