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.
Answer:
-2 by 1
Step-by-step explanation:

For #2, the proportion would be .40/.25 and x/15, then you would cross multiply to find x. and for #3 the proportion would be 15/6 and 75/x and again you would cross multiply to find x. (:
All linear dimensions of similar figures are in the same ratio.
The perimeters are also in the ratio of 5 to 4.
General equation is
an = a1 + (n-1)d where a1 = first term and d = common difference
here d= 2-5 = -3 and a1 = 5
so an = 5 -3(n-1) is the explicit equation required.
