Convert decimal to fraction
a^2+(21/10)^2=2.9
Use exponent rules
a^2+441/100=2.9
Move constant to the right
a^2=2.9-441/100
Calculate
a^2=-151/100

Evaluate 3 - (-1) + (-1) - 3.

Answer:

Step-by-step explanation:

3 - (-1) + (-1) -3 =

Minus and a negative makes it positive. In other words it would be written like this: 3 + 1 + (-1) - 3 =

Next step would be making it minus 1, because plus sign and negative makes the number to be subtracted. It would be rewritten like this: 3 + 1 - 1 - 3 =

Then you will simply add 3 and 1, which makes it 4. So it would be rewritten likes this: 4 - 1 - 3 =

Then you will simply subtract 1 from 4, which would equal to 3. So it would be rewritten like this: 3 - 3 =

Last step, would be subtracting 3 from 3. Whatever is subtracted from itself would always be 0.

So the answer would be 0!
