Answer
Find out the the total length of the walking trail .
To prove
Formula

As given
The trail starts at R(−3, 2) and goes to S(2, 2) and continues to T(2, −5).





RS = 5 units
As given
S(2, 2) and continues to T(2, −5).
Now




ST = 7 units
Therefore
Total length of the trail = RS + ST
= 5 units + 7 units
= 12 units
Therefore the total length of the trail is 12 units.
Answer:

Step-by-step explanation:
I don't know what level math you're taking but in lower level math this would be undefined, can't be simplified. But some higher levels simplify it with imaginary or complex number representations. So take your pick, but it's still undefined
Prime numbers below 30: 1, 3, 5, 7, 11, 13, 17, 19, 23, 29
2 prime numbers that sum up to 30:
1 and 29
7 and 23
13 and 17
The greatest possible product will be 13 x 17 = 221
Answer: The two prime numbers are 13 and 17
