Question

if 2k+2m+12, km=3, find the value of 4k^2+9m^2

Answer 1

Step-by-step explanation:

I think...........

Given,

km = 3

k = 1/3m

Now,

2k + 2m = 12

2(k+ m) = 12

k + m = 6

1/3 m + m = 6

m +3m = 18

4 m= 18

m = 9/2

Therefore,

k = 1/3 × 9/2 = 3/2.

Value of 4k^2 + 9m^2

= 4×(3/2)^2 + 9× (9/2)^2

= 9 + (729/2)

=747/2...
