Because 20^2+21^2=c^2
To answer this question you always need to look at the number before it; if its 5 or higher you round up and if it's 4 or lower you round down. So the answer is 100,000 since the number before is 0.
<span>Hello, Yoloalanis. In order to solve this question that you have just posted, you only have to do a few simple steps. So, We can do this!</span>
<span />Let's start with your fraction. You will first have to change 9/12 into a decimal. In order to do this, you will have to divide the numerator by the denominator. A numerator is also known as the top part of the fraction. A denominator is the bottom part of the fraction. So, when you divide nine by twelve, you get 0.75 as a decimal. Now, you just have to multiply the decimal by 100 or to make it simpler, just move the decimal two places to the right. To sum it all up, you will get 75%.
Hope it helps :)
15r^2 - 14r -12 is the correct answer
