Б) 3х2 – 10 = 152<br>how to solve with square root​
Tju [1.3M]

Answer:

3\sqrt{6}  and  -3\sqrt{6}

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}

Now, we need to reduce the radical by using the rule shown below:

\sqrt{x*y}=\sqrt{x}  \sqrt{y}

Now,

\sqrt{54}=\sqrt{6*9} =\sqrt{6}  \sqrt{9} =3\sqrt{6}

The correct answer is  3\sqrt{6} and -3\sqrt{6}

<u>Note:</u> squaring positive and negative makes the same answer

Help me with this question please ? and how do I get the answer?
melamori03 [73]
1) you have to find the difference between pipe A and pipe B, which is 6.40.

23.55-17.15=6.40

2) after finding the difference. You will take that difference and put it out of 23.55 and multiply by 100 to get your percentage. As so:

(6.40/23.55)(100)= 27.176% which rounds to 27% as a whole number.

Your answer is 27%. Hope that helps!
