Answer:
-4x^2+3x
Step-by-step explanation:
collect like terms
(2x^2-6x^2) + (6x-3x) + (5-5)
simplify
-4x^2 + 3x
So kind man so kinda dude
v = hvh
Simplifying the above equation:
v = h × v × h
Taking the RHS 'v' to LHS
⇒ v ÷ v = h × h
⇒ 1 = h × h
⇒ 1 = 
⇒ h = √1
⇒ h = 
So h can have the values +1 or -1.
Putting h = +1 in the equation,
v = (+1) × v × (+1)
⇒ v = v
Hence, v can take any integer value.
Putting h = -1 in the equation, when h = 1.
v = (-1) × v × (-1)
⇒ v = v
Hence, v can take any integer value when h = -1.
Hence, as long as h is either +1 or -1, v can take any integer value.
The distance between two cities is

assuming you mean 30.5 and 10 feet, the height is 15 feet.
Step-by-step explanation:
Volume = length X width X height
so
4,575 = 30.5 X 10 X height
4,575 = 305 X height
4,575 / 305 = height
15 equals height
