Answer:
P(n,4)÷P(n,2)
= (n-2)(n-3)
20 = 4 × 5 (two consecutive numbers)
(n-2)(n-3)=5×4
n-2=5
n=7
Answer:
h = √72 in.
Step-by-step explanation:
Height of the cone using pythagorean theorem, a² + b² = c², where:
a = h
b = ½(6) = 3 in.
c = 9 in.
Plug in the values
h² + 3² = 9²
h² + 9 = 81
h² + 9 - 9 = 81 - 9
h² = 72
h = √72
90=6x+3x
90=9x
90/9=x
10=x
3x=3*10=30
6x=6*10=60
hope this helped
