Indicate the general rule for the arithmetic sequence with a3 = -12 and a8 = -37. an = -2 + (n-) an = -2 + (n-1)(5) an = 2 + (n-) an = 2 + (n-1)(5)

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

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
