ANSWER
EXPLANATION
Use the Pythagoras Theorem to obtain,
This implies that,
Take the positive square root of both sides to get,
Answer:
The answer would be 22/12 or 1 and 11/12
Step-by-step explanation:
1/2+2/3+3/4
First get common denominators so you have a denominator of 12 so 6/12+8/12+9/12
Add those together and you get 23/12 but you have to subtract one because that's what the problem says so you get 22/12
10(4^2-(9)
Since 16-9 is 7
And 10 times 7 is 70
