The perimeter of the quadrilateral is 39 centimeters. Find the length of each side. x+9
(x²–2x
x+4
3x-2
Side one = x + 4 = 8 cm
Side two = x+9-13 cm
Side three-X? - 2x
2x-1cm

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
