The second option: The student should have distributed and written -2x+5, not -2x-5.
That’s because the two negatives make a positive when multiplying/distributing.
Step-by-step explanation:
Rational numbers are numbers that terminate or are a repeating decimal.
4 rational numbers between -1/3 and -1/2 are
-5/12,
-0.583333333333333333333333333...,
-0.54166666666666..., and
-0.5208333333...
Hi!
<h3>An irrational number is a number that cannot be written as a ratio or a fraction. </h3><h3>Let's go through each answer. </h3>
= 0.18973666...
<u>This is irrational, because it repeats forever.</u>
<u>This is rational, because 2525 repeats in a pattern.</u>
= 1
<u>This is rational. (1/1)</u>
<u>This is rational (10/1)</u>
<h2>The answer is A. √0.036.</h2>
Hope this helps! :)
