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

Step-by-step explanation:
Use the quadratic formula to solve for all real solutions.
Quadratic formula:
Plug in and solve:
Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:

40(7.85) = 314
314 - (32.24 + 24.02 + 24.53) =
