To answer the question, combine the terms having the same nature of variables in the given above,
(2x²y + 3x²y) + 3x² + (4y + 2y)
The simplification of the expression leads to the answer,
5x²y + 3x² + 6y
Answer: 
Step-by-step explanation:
Given : Hot air balloons generally descend at a rate of 200 to 400 feet per minute.
Also, Four balloons descend 200 feet per minute for 9 minutes.
Then, the total change in altitude for all 4 balloons will be :-
Hence, the total change in altitude for all 4 balloons will be : Balloon descends 18 feet in 4 minutes.
Point slope is y-y1= m(x-x1) where m is slope
Plug the values in:
y-(-8)=3(x-8)
Simplify:
y+8=3(x-8)
Yes you do because you cannot subtract 7 from 6.
Okay, so if your rectangle is 16 by 8, that means that the circle diameter of 8 because that would be outside of the card's width,
the area of the rectangle is 16 x 8 or 128
the radius of the circle would be 4 (because 1/2 of the diameter is radius)
we know that the equation of the circle PIr^2, so the area of the circle is 16PI
then, the remaining area would be calculated by 128-16PI
This comes out to be approximately 77.73
