T - 2(3 – 2t) = 2t + 9

t=-1

Step-by-step explanation:

t - 2(3 - 2t) = 2t - 9

t - 6 + 4t = 2t - 9

5t - 6 = 2t - 9

5t - 2t = -9 + 6

3t = -3

t= -1

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
