Answer:
Option C
1.62 and -0.62
Step-by-step explanation:
v² - v - 1 = 0
From ax² + bx + c = 0
a = 1 b = -1 c = -1
Quadratic formula
x = -b +/- √b² - 4ac
--------------------------
2a
x = -(-1) +/- √-1² - 4 x 1 x -1
-----------------------------------
2(1)
x = 1 +/- √1 +4
-----------------
2
x = 1 +/- √5/2
x = 1 + √5/2 or x = 1 - √5/2
x = 1.618 or -0.618
Hello!
To find the perimeter you add all the sides
Since the pool table has 4 sides ( 2 lengths and 2 widths)
We can do 5 + 5 + 8 + 8 = 26ft
Hope this helps!
