To find the perimeter you would add all the sides of the triangle together.  Represent the length of each side using the information given.

1 side =  x
2 side = x
3 side = 2x - 2

Add these together and combine the like terms.

x + x + 2x -2; the bold parts are the like terms

4x - 2 represents the perimeter.

X = y - 8

Step by step
Y = x + 8
x + 8 = y
-8 -8
x = y - 8

Need help asap please!!<br> This is the only one i don’t know i’m stuck!

Answer:

Reminder that is this form  a(b)^x  where  a > 0

When   b > 0  but < 1 that is a decay function

When   b > 1 than its a growth function

Step-by-step explanation:

So following this you can figure out the answer

g(x)=0.3(x)      

this is neither since there is no exponent (linear)

H=72(56)^t    

this is growth since b  = 56

A=(43)^t        

this is growth since b  = 43 ("a" is understood as "1")

H=5.9(0.82)^t      

this is decay since b =  0.82

y=0.8(3.6)^t      

this is growth since b = 3.6

f(t)=0.72(15)^t    

this is growth since b  = 14  

A=49(8)^t      

this is growth since b  = 8
