Answer: It is true, I explained it down below in the picture.
Step-by-step explanation:
I would say that the unfinished puzzle has more than one piece and the missing piece is only one, itself.
A^2 - b^2 = (a - b)( a +b);
<span>cos^4x-sin^4x =( cos^2x + sin^2x )( cos^2x - sin^2x) = 1* cos2x = co2x.</span>
The number would stay the same because, for example, 6 - 0 can't be 0 so it would be 6.
Answer:
False
Step-by-step explanation:
Unit Rate Definitions Unit rate is used to compare quantities in which the second quantity is one. Common examples of unit rate would include, miles per hour earnings per hour cost per gallon.
