P = 2(L + W)
P = 200
L = 2W + 4
200 = 2(2W + 4 + W)
200 = 2(3W + 4)
200 = 6W + 8
200 - 8 = 6W
192 = 6W
192/6 = W
32 = W <== the width is 32 ft
L = 2W + 4
L = 2(32) + 4
L = 64 + 4
L = 68 <=== the length is 68 ft
Answer:
A.
Step-by-step explanation:
y=loga(x) is just the same as x=a^y
Answer:
A. The difference in the heights of the bars will not appear as great.
Step-by-step explanation:
2x^2-7x-4=0
2x^2-8x+x-4=0
2x(x-4)+1(x-4)=0
(2x+1)(x-4)=0
x=-1/2, 4
use the quotient rule then after using it the first time use it again on your resulting equation, since you are looking for the second derivative
