Answer:
C.) 5, 12, 13
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides must equal the square of the longest side (Pythagoras).
a² + b² = c²
We can test each set of numbers to see which one fits.
A.) 8² + 12² = 16²
64 + 144 = 256
208 ≠ 256
B.) 6² + 7² = 8²
36 + 49 = 64
85 ≠ 64
C.) 5² + 12² = 13²
25 + 144 = 169
169 = 169
The numbers 5, 12, and 13 could represent the lengths of the sides of a right triangle.
D.) 16² + 32² = 36²
256 + 1024 = 1296
1280 ≠ 1296
If the initial time was 60 seconds and 18 seconds have passed,

There would be 42 seconds left.
Answer:
-31 1/3 (answer choice 1)
Step-by-step explanation:
Let's begin by eliminating the fractions. Mult. all four terms by the LCD (8), obtaining:
-f - 6 - 2f = 88. Then -3f = 94, and f = -31 1/3
