Answer:
27.5
Step-by-step explanation:
first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.
so!
30x30 is 900
12x12 is 144
subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5
The answer is maybe C lol
Add the 7 and 4, which =11.
multiply times the 5, =55
and 20-55= -35
The solution of the given Inequality is; D: x ≤ 6
<h3>How to find the solution of an Inequality?</h3>
We want to find the solution to the Inequality;
5x - 9 ≤ 21
Using Addition property of equality, add 9 to both sides to get;
5x ≤ 30
Using division property of equality, divide both sides by 5 to get;
x ≤ 6
All real numbers less than or equal to 6
