X^2 -5x -20=0
(x - 5/2)^2 -20 -25/4=0
(x-5/2)^2-105/4=0
(x -5/2 -(105)^1/2)(x -5/2 +(105)^1/2)=0
factors are (x -5/2 -(105)^1/2) and
(x -5/2 -(105)^1/2)
2 cups of gravy. Because when you have 4 that is just adding an extra 2 and since gravy comes for every 2 it is going to be 2 cups of gravy.

Height of the flagpole before it broke was 32 m
Step-by-step explanation:
- Step 1: This forms a right angled triangle with height 7 m and base 24 m. Find the hypotenuse using the Pythagoras Theorem.
Hypotenuse² = Base² + Height²
= 24² + 7² = 576 + 49 = 625
∴ Hypotenuse = √625 = 25 m
- Step 2: Find the height of the flagpole before it broke.
Since the stuck 7 m and the remaining part which is the hypotenuse together make the flagpole.
⇒ Height = 7 m + 25 m = 32 m
