Question

5x + 1/3x =4 then 9x^2 + 1/25x^2 =?

Answer 1

Answer:

Step-by-step explanation: The answer is quite simple. You just have to multiply the right hand side and the left hand side with 3/5.

The equation becomes:

3/5(5x + 1/3x) = 12/5

3x + 1/5x = 12/5

Now squaring both sides, you will get

9x^2 + 1/25x^2 + 6/5 = 144/25

Therefore, 9x^2 + 1/25x^2 = 114/ 25

Answer 2

Concept introduction:

This question is based on an equation in which we have to solve the given equation and conclude the final answer.

Step-by-step explanation:

To find:

We have to multiply the right hand side and the left hand side with 3/5.

Solution:

According to the question,

3/5(5x + 1/3x) = 12/5

3x + 1/5x = 12/5

Now squaring both sides, you will get,

9x^2 + 1/25x^2 + 6/5 = 144/25

Therefore, 9x^2 + 1/25x^2 = 114/ 25

Final answer:

9x^2 + 1/25x^2 = 114/ 25
