Which of the following is a Recursive Formula for an Arithmetic Sequence? a1 = -3, an = 4an-1
a1 = -3, an = an-1 + 4
an = -3 + 4(n – 1)
an = 4n – 7

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

step-by-step explanation:

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
