Question

If 2x+1/3x =4 than 9x^2 +1/4x^2 =?
​

Answer 1

Answer:

Ans must be 141. Let 2x=a and 1/3x=b. In the given eqn divide both sides by (ab). In doing so on LHS you will get 1/a+1/b=8/(ab).On further simplication, 3x+1/2x=12. Now square both sides. We get, (9x^2)+(1/4x^2)+3=144 =>Ans is 141

Answer 2

Answer:

the answer is 36.1406250

Step-by-step explanation:

I got this answer because

2x divided by 3x equals .666666666666. So 9x=6 squared which is 36+ 1/.375=0.1406250
