Given 30(0.7)^x/3
What would be the starting point and rate of change?
A)30,0.7
B)30,3
C)3,0.7
D)0.7,3

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

the answer to this is a. a^2 + b^2 = c^2
