Answer:
The area of the rectangle is increasing at a rate of 
.
Step-by-step explanation:
Given : The width of a rectangle is increasing at a rate of 2 cm/ sec. While the length increases at 3 cm/sec.
To find : At what rate is the area increasing when w = 4 cm and I = 5 cm?
Solution :
The area of the rectangle with length 'l' and width 'w' is given by 
Derivative w.r.t 't',
Now, we have given
Substitute all the values,
Therefore, the area of the rectangle is increasing at a rate of .
1.5 because it is more!!!!!!!!!!!!!!!!!!!!!!!
Answer:
2s/n-a=L
Step-by-step explanation:
So first we divide (n÷2) so it will be s/(n÷2) =a+L. Next we subtract L and get s/(n÷2)-a. That's not it yet, since 2 is being divided in the denominator, we have to reciprocal it meaning multiply, it to the top value. So it would 2s/n-a=L. But you can just leave it like that if you desire and your teacher doesn't mind.
Answer: 8X - 2 I believe
Explanation: If you add 3X + 5X you get 8X since you can’t add them with the whole numbers without a variable. After that you add 4 + -6 (4 - 6) either that or its 8X + 10
