Answer:
hello your question is incomplete attached below is the complete question
answer : 54 m
Step-by-step explanation:
Applying jet equation of Parabola
(x-h)^2 = 4p (y-k) where (h,k) = 0
x^2 = 4py and this passes through ( 48, 24 )
(48)^2 = 4(p)(24)
hence P = 24
x^2 = 96h at x = 72 and y(h) unknown
= 72^2 = 96(h)
h = 72^2 / 96 = 54 m

Step-by-step explanation:
In this question we will do the factors of given two terms then we will do the common factors of all the terms given in answer to match with.
Common factors of 36h³ = 1×2×2×3×3×h×h×h
Common factors of = 1×2×2×3×h×h×h×h×h×h
In these two terms greatest common factor Of these two terms is = 1×2×2×3×h×h×h = 12h³
Therefore the third term will be the number which has the greatest common factor = 12h³
So the given terms are
6h³ = 1×2×3×h×h×h
12h² = 1×2×2×3×h×h
= 1×2×3×5×h×h×h×h
= 1×2×2×2×2×3×h×h×h×h×h
Therefore the greatest common factor of the term which matches with 12h³ is
