-10/-16 could be an answer or multiply the same number up and down but the number must be negative
1/2÷ 3/8=4/3. To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
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
X=4 x=-4 Due to the difference in squares theorem
The answer is: 0.21768707483
