Answer:

39

Step-by-step explanation:

You need to solve the exponents first

3[64÷(25 -9)+9]

Then you can do the parenthesis

3[64÷ 16 +9]

Then divide 64 by 16 which equals 4

3[4+9]

Then you do the brackets

3 x 13

Which equals 39

Answer:

39

Step-by-step explanation:

Use PEMDAS.

Starting equation:

3[8^{2}/(5^{2}-3^{2} )+9]

Start with evaluating the Exponents inside the innermost Parentheses:

3[8^{2} /(25-9)+9]

Evaluate the Subtraction inside the innermost Parentheses:

3[8^{2} /(16)+9]

Now that we have solved the first set of Parentheses, we need to solve the second, starting with the Exponents:

3[64/16+9]

Next, we need to evaluate the Division inside the Parentheses:

3[4+9]

After that, evaluate the Addition inside the Parentheses:

3[13]

Finally, evaluate the Multiplication:

3[13]=39

The answer is 39.

Simplify 2x + x<br> o 2x2<br> 3x<br> O 3x²
DochEvi [55]

Answer:

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   2 • 2 = 4  

Step-2 : Find two factors of  4  whose sum equals the coefficient of the middle term, which is   3 .

     -4    +    -1    =    -5  

     -2    +    -2    =    -4  

     -1    +    -4    =    -5  

     1    +    4    =    5  

     2    +    2    =    4  

     4    +    1    =    5  

Observation : No two such factors can be found !!

2.199 rounded to the nearest whole number
steposvetlana [31]
Rounding 2.199. The tenths digit is 1, which is 4 or less, so you will round down. Re-write 2.199 without the decimal places: 2 . So 2.199 rounds to 2.
