W=2L-5
-------------
A=L*W
=L(2L-5)
=2L²-5L
-------------
dA/dL=4L-5
When dA/dL=0,
4L-5=0
4L=5
L=5/4
----------------
When L=5/4
A=5/4*(2*(5/4)-5)
=5/4*(10/4-20/4)
=5/4*((-10)/4)
=5/4*(-5/2)
=-25/8

*You may have been given a badly written out question. The answer doesn't make sense.
Since we know 16 ounces equal a pound, we just need to divide 72 by 16.
72/16 = 4.5
Your answer should be 4.5 pounds. Hope this helps!
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:
Answer:
72 beats per minute
Step-by-step explanation:
Given data :
Original pulse rate = 80 beats per mint
Reduction = 10%
Decrease in the number of beats per minute = 80 × 10/100 = 8
Hence, new pulse rate = 80 - 8 = 72 beats per minute.
Thus, the new pulse rate will be 72 beats per minute
It would have to be number 2) x-3
