Write the explicit rule. remember to simplify and do not put spaces in your answer. sequence : 32,52,72,92...

a n =

a(n)= 12x+20

Step-by-step explanation:

tbh I'm not sure if this is the form they wanted it in but assuming this is an arithmetic sequence you can find the equation by finding the n-1(assuming 32 is the first term 12 would be the zero term) term and then adding the common difference(20) to get 12x+20.

However that might be the recursive way so do double check your options.

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
