You would write it out 7.83
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>
Answer:
What are the options?
Step-by-step explanation:
Answer:
2.06 is smallest ans 2.9 is largest
Step-by-step explanation:
3x-3y=4
3y= 3x -4
y= x-4/3
-3x+3y=3
3y= 3x+3
y= x +1
.....
Since they have the same slope and different y-intercepts , then there are no solutions for these equations because they're parallel.
