(6x^4) + (15x^3)(y^2) + (3x^2)(y^3) is your answer
As we are looking at descending powers of x. Look at the powers of the x. In the first one (6x^4), the power is 4, and 4 is greater than the other numbers given (3 & 2). Therefore, the order given above is correct.
hope this helps
The answer to that is 7 but i dont get the last part
Slope intercept form means that you have to solve for y.
Subtract 5x from both sides
5x - 6y - 5x = 22 - 5x
= -6y = 22 - 5x
Then divide by -6
-6y/-6 = 22/-6 - 5x/-6
= y = -22/6 + 5x/6
You can reduce the fraction -22/6 to -11/3
y = -11/3 + 5x/6
Then swap the order of your terms so it looks nicer and you don't have a negative in front
y = 5x/6 - 11/3
To subtract fractions, find the LCD and then combine.

Answer:
The area of rectangle is changing at the rate of 33 square inches per second.
Step-by-step explanation:
We are given the following information:
Let W be the width of the rectangle and L be the length of rectangle.
Rate of change of width = 
Rate of change of length = 
We have to find rate of change of area at W = 2 and L = 3.
Rate of change of area = 
Area of rectangle = Length × Width
Putting the values, we get
The area of rectangle is changing at the rate of 33 square inches per second.
