A varies BC, when b=4,and c=9,a=6

Question

a.find the formulea connecting A,B and C.
b.find A whenn B=3 and C=10
c.find C, if A=20 and B=15

Answer 1

Could you clarify what you mean by "A varies BC" please? I feel there's more to this question than reproduced here.

Answer 2

did you mean
A vavies with BC or A varies directly with BC, if so, then

a. A = kBC

so, 6 = k(4)(9)
k = 6
then A = 6BC

b. A = 6(3)(10) = 180

c. 20 = (6)(15)C
C = ......

Answer 3

Ummn

Just wanna say thank u very much

Answer 8

Answer 10

a) A=KBC
6=k4(9)
6/6 =k36/6
K=6
b)

Answer 11

1 A=1/BC
A=k/BC
6=k/36
K=6/36
K=1/6
A=BC/6
2 A=BC/6
A=3×10/6=5
