If \(M=\frac{at^2}{h}\) and \(M \neq 0\) what is the effect on M of doubling t, tripling a, and quadrupling h?
A. M is multiplied by 1.5.
B. M is multiplied by 3.
C. M is multiplied by 4.
D. M is multiplied by 4.5.
E. M is multiplied by 79.
Kudos for the right answer and explanation

If we double t, triple a, and quadruple h we have
(3a)(2t)^2 / (4h)
= 3(a)(4t^2) / (4h)
= 3*4(a)(t^2)/ 4*h
= 3 (a)(t^2) / h
= 3 M
So it triples.
(3a)(2t)^2 / (4h)
= 3(a)(4t^2) / (4h)
= 3*4(a)(t^2)/ 4*h
= 3 (a)(t^2) / h
= 3 M
So it triples.
