Answer:

a) \:  \: 6x - 8

b) \:    \: - 18 {x}^{2}  + 15

c) \:  \:  {x}^{4}  + 2  {x}^{3}  + 7 {x}^{2}

Step-by-step explanation:

a) \:  \: 2(3x−4) \\ 2(3x)+2(−4) \\ 6x+2(−4) \\ 6x−8

b) \:  \: −3(6 {x}^{2} −5) \\ −3(6 {x}^{2} )−3( - 5) \\  - 18 {x}^{2}  - 3( - 5) \\  - 18 {x}^{2}  + 15

c) \:  \:  {x}^{2} ( {x}^{2}   + 2x + 7) \\  {x}^{2}   {x}^{2}  +  {x}^{2} (2x) +  {x}^{2}  \times 7 \\  {x}^{4}  + 2 {x}^{2} x + 7 \times  {x}^{2}  \\  {x}^{4}  + 2  {x}^{3}  + 7 {x}^{2}

How much pure water must be mixed with 10 liters of a 25% acid solution to reduce it to a 10% acid solution?
elena-s [515]

Suppose you add x liters of pure water to the 10 L of 25% acid solution. The new solution's volume is x + 10 L. Each L of pure water contributes no acid, while the starting solution contains 2.5 L of acid. So in the new solution, you end up with a concentration of (2.5 L)/(x + 10 L), and you want this concentration to be 10%. So we have

\dfrac{2.5}{x+10}=0.1\implies25=x+10\implies x=15

and so you would need to add 15 L of pure water to get the desired concentration of acid.
