Answer:
B
Step-by-step explanation:
5a^2 - 44 = 81 Add 44 to both sides
5a^2 = 81 + 44 Collect like terms
5a^2 = 125 Divide both sides by 5
a^2 = 125/5
a^2 = 25 Take the square root of both sides
√a^2 = √25
a = +5
a = -5
The answer is B

The product could be either less than or greater than 67,124.
If you multiplied by a negative number, you would get a negative number, which is less than a positive number such as 67,124.
If you multiplied by zero, you would get zero, which is less than a positive number such as 67,124.
If you multiplied by one, you would get 67,124, which is equal to 67,124 since they are the same number.
If you multiplied by a positive number less than one, you would get a positive number greater than zero and less than 67,124.
If you multiplied by a positive number greater than one, you would get a positive number greater than 67,124.
Answer:
Step-by-step explanation:
Look at the 3rd decimal digit (the digit after the hundredths).
- if it is the digit is less than 5 then round the number down by taking away the decimal point of the number after the 2nd decimal place;
- However if it is 5 or more then round the number up by adding one on to the hundredths digit and removing the rest of the decimal part of the number after it
For example,4.749 rounds up to 4.75 because the 3rd decimal digit is a 9.
I hope this helps ^^
