Answer:
k = 31
Step-by-step explanation:
17 = (-14) + k
Add 14 to both sides
k = 31
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.
Answer:

Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Mathematically, this is

In this problem, we have that:
Desired outcomes:
There are 52 cards, of which 13 are diamonds.
We want non diamond cards, so 
Total outcomes:
Deck of 52 cards, so 
Probability

N /(n*10^n)
So 3 would be
3/(3×1000)=1/1000=.001
