Answer:

$3(4 {x}^{2} {y}^{3} + 2 {x}^{3}) - 4(9 {x}^{3} {y}^{2} - 6 {x}^{2} {y}^{3} ) \\ = (12 {x}^{2} {y}^{3} + 6 {x}^{3} ) - (36{x}^{3} {y}^{2} - 24{x}^{2} {y}^{3}) \\ = (12 {x}^{2} {y}^{3} + 6 {x}^{3} ) + ( - 36{x}^{3} {y}^{2} + 24{x}^{2} {y}^{3}) \\ = - 36{x}^{3} {y}^{2} + 36x^{2} {y}^{3} + 6 {x}^{3}$

Vilka [71]

Answer:

The quantity of acid in the solution is 47.1 ml

Step-by-step explanation:

Given as :

The quantity of solution of acid and water = 357 millimeters

The percentage of acid in the solution = 13.2 %

Let the quantity of acid in the solution = x ml

<u>So, According to question </u>

13.2 % of the total quantity of acid in the solution = x

I.e x = 13.2 % × 357

Or, x = $\frac{13.2}{100}$ × 357

Or, x = 0.132 × 357

∴ x = 47.124 millimeters

So , The quantity of acid = 47.1 ml

Hence The quantity of acid in the solution is 47.124 ml Answer
