Answer:
In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials.
In any linear equation the coefficient of the x-term represents ALWAYS the slope.
So it is B. The slope of the line
Answer:
Step-by-step explanation:
For any triangle, the Law of Cosines is given by 
, where all three variables are interchangeable.
Therefore, we have:
Answer: = 240 mph.
Step-by-step explanation:
Let x = speed of the plane.
t= time taken
As per given, we have
[Time = distance / speed]
From (i) and (ii), we get
Hence, the speed of the plane = 240 mph.
The length is 6/5 of the width, which is 12. so you multiply them, 6/5 times 12/1 and you get 72/5 which simplifies to 14 and 2/5 or 14.4. so your length is 14.4. which means your perimeter is 52.8 inches. and to get the area you just multiply 12 by 14.4 and you get 172.8. so your perimeter is 52.8 and your area is 172.8
