<span>(-7) = e/3 + 14
Subtract 14 on both sides
-7 - 14 = e/3 + 14 - 14
-21 = e/3
Multiply by 3 on both sides
-21 * 3 = e/3 * 3
-63 = e</span>

Answer:
Length = 10 & width = 3
Step-by-step explanation:
Perimeter = Length + Length + Width + Width
26 = 2Length + 2 Width
26 = 2 ( Length + Width )
13 = Length + width
13 - Length = Width EQUATION 1
Area = Length X Width
30 = Length X ( 13 - Length )
30 = 13Length - Length ^2
Length ^2 - 13Length + 30 = 0
( Length - 3 )( Length - 10 )
Length = 3 or Length = 10
Therefore Length = 10
From equation 1
13 - Length = Width
13 - 10 = width
width = 3
volume of a cylinder is area of the base times the height
diameter 8 means radius r=4
V = πr²h = π(4²)(10) = 160π
Answer: 160π cubic meters
It's not clear if you need an approximation; I'll leave the calculator stuff to you.
Answer:
Net_change_in_depth = 450/7 ft = 64 2/7 ft
Step-by-step explanation:
Missing info attached below
Depth_of_the_frequency_signal = -180 4/7 ft = -1264/7 ft
Depth_of_the_submarine = -116 2/7 ft = -814/7 ft
Net_change_in_depth =
Depth_of_the_submarine - Depth_of_the_frequency_signal
Net_change_in_depth = -814/7 ft - (-1264/7 ft)
Net_change_in_depth = 450/7 ft = 64 2/7 ft
