Answer 1
Answer: x^2 + 16 = 8x\n\nx^2-8x+16=0\n\nx^2-4x-4x+16=0\n\nx(x-4)-4(x-4)=0\n\n(x-4)(x-4)=0\n\n(x-4)^2=0\ \ \ \Leftrightarrow\ \ \ x-4=0\ \ \ \Leftrightarrow\ \ \ x=4\n\n Ans.\ One\ solution
Answer 2
Answer: Every equation that has an ' x² ' in it has two solutions.

If it's a perfect square, then the solutions are equal, and they look like only 1.

Both solutions to this equation are [ x = 4 ] .

What is 164 rounded to the nearest 10

Answers

The rounded off to the nearest ten of 164 is 160.

What is rounded off?

The process of putting a number up or down to the nearest whole number or the nearest hundred, thousand, etc., is called rounded off.

Given that. 164 rounded to the nearest ten,

To round to the nearest ten we consider the last digit of the number, if it is less than 5 we round down and if greater than 5 we round up,

Here, the number is 164 and the last digit is 4 which is less than 5, hence, we will round down 164,

164 = 160

Hence, the rounded off to the nearest ten of 164 is 160.

If the ones place is below 5 it is rounded down, and if the ones place is 5 or greater you round up. 164 has 4 in the ones place, which is less than 5, so you round down to 160.

 

Is 0.602 equvalent to 0.62

                

Answers

No.
0.602 = 0.6020 = 0.60200 etc
0.62 = 0.620 = 0.6200 etc
Adding zeros to the end of a decimal doesn't change the value, the order of the digits does.
No.. 0.62 is a larger number than 0.602

Anyone please help me with this question.

Answer:

The answer is 207 miles per hour

Step-by-step explanation: You can find this answer by taking 332 and converting it to a fraction and then multiplying it by 5/8. That would look like this 332/1 X 5/8 = x. Then you multiply then numerators, then denominators and simplify the fraction. Next you can divide the numerator by the denominator. And once you have this you round to the nearest whole number.

Hope this helps.

The average person lives 78 years Does the average person live for at least 1,000,000 hours?

Answers

First we will divide to see how many years will come in the amount of days,

1,000,000 ÷ 365 ≈ 2,740

SO, in 1,000,000 days there are ABOUT 2,740 years. 

Next we will multiply  to see how many days there are in 78 years.

365 × 78 =  28,470

SO, there are 28,470 days in 78 years. 

No, the average person lives more than 1,000,000 days. 

Hope I helped ya!! 

I just answered this fore someone, a couple of days ago! 
No the average person lives longer.
60 x 24 = 1,440
1,140 x 365 = 525,600
525,600 x 78 = 40,996,800
Which is more than 1,00,000
