Answer:
No
Step-by-step explanation:
To determine if the 3 sides form a right triangle.
Use the converse theorem of Pythagoras.
If the square of the longest side is equal to the sum of the squares of the other two sides then the triangle is right,
longest side = 14 and 14 ² = 196
9² + 12² = 81 + 144 = 225
Since 196 ≠ 225 the triangle is not right
10 weeks, 10 times 2 is 20, and 5 times 10 is 50, divided by 2 is 25, add 20 to 25 which is 45
The answer to that question is 4
