Answer:
7 1/2
Step-by-step explanation:
i belive so my brain hurts so much but i can pull through
To be a triangle
1)sum of two sides should be more than 3d side,
2) 3d side should be more than difference of two other sides.
5+13 > x, ----> x < 18
13 - 5 < x, -----> x > 8
8< x < 18
It looks like only one value of the side can create a triangle,

<span>-1.5*N/-1.5=-1.2*-1.5
n = 1.8

The general term is obtained by starting with the initial value 5 and then subtracting 4 each time you wish to generate a new term:
a2 = second term = 5+(2-1)(-4) = 5+(-4) = 1
General term:
an = nth term = 5+(n-1)(-4)
Thus, the 21st term is 5+(21-1)(-4) = 5 + (20)(-4) = -75 (answer)
-7p=-2-6p
7p=2+6p
p=2
Hope this helps :)
