Step-by-step explanation:
The numbers that can be used to form triangles are collectively called "triangle numbers." The n-th triangle number is the sum of all numbers less than or equal to n. It is ...
n(n+1)/2
For n=14, the number is 14(15)/2 = 7·15 = 105.

Answer:
Step-by-step explanation:
width = w
L = 5w - 6
w(5w - 6) = 18
5w^2 - 6w = 18
5w^2 - 6w - 18 = 0
Using the quadratic equation formula
x = 2.58997 and
x = -1.38997 This root cannot be. (No rectangle has a minus length.
w = 2.58997
L = 5*2.58997 - 6
L = 6.94985
w = 2.59
L = 6.95
