Answer:
12 km
Step-by-step explanation:
Using the formula <em>rate × time = distance:</em>
Jogging = 12 km/h × x = 12x
Walking = 8 km/h × (x + 0.5) = 8x + 4
Setting the two terms equal:
12x = 8x + 4
Subtracting 8x from both sides:
4x = 4
Dividing both sides by 4:
x = 1
Therefore, it takes 1 hour of jogging or 1.5 hours of walking to travel from the school to the pool. Thus, they are 12 km [12 km/h × 1 h <em>or</em> 8 km/h × 1.5 h] apart.
(x-11)(x+11). Mark as branliest tq.

<h3>What is octagon ?</h3>
- A polygon of eight angles and eight sides.
- It has eight lines of reflective symmetry and rotational symmetry of order 8. A regular octagon is represented by the Schläfli symbol {8}.
- The internal angle at each vertex of a regular octagon is 135° ( radians). The central angle is 45° ( radians).
each side of house = 22 feet long
Perimeter of octagon = 8 × sides
Length of each side of house = 8 × 22 ⇒ 176 feet²
Therefore, length of each side is 176 feet ² .
