Answer:
It is 30 because it is the only one that makes sense if you do the math
Answer:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Answer:
14
Step-by-step explanation:
- Square root of (x2-x1) squared + (y2-y1) squared
- which is square root of (8-8) squared + (-16-(-2)) squared
-simplify it, then get 14
It’s a rational number when you round it to any place value, if you don’t round, it’s not rational.
Rational numbers are fractions and decimals that don’t go on and on forever, and no fractions that are over 0.
Since .3333 doesn’t go on forever, it’s rational.
It’s rounded to the Ten Thousandths.
Examples:
Rational: 4/5 .35 6/8
Not Rational: .3333333 (forever) 4/0 6/0 .555555 (forever).
Hope this helps :)
