Answer:
49
Step-by-step explanation:
We will need the Perimeter formula to find this out. The perimeter of the square in this problem is 196 for the soldiers. P=4a, 196=4a. Divide both sides by 4. 49 = a, so 1 side is 49.
<span>f(x) =-(x+9)(x-21)
Manipulating algebrically,
We get,
</span>f(x) =-(x+9)(x-21)
= -(x^2 -21x + 9x - 189)
= -(x^2 -12x - 189)
= -x^2 + 12x + 189
Axis of symmetry = -b/2a
plugging the values,
x = -12/-2
= 6
