Hi! i was wondering if someone could help me with this that would be awesome I will try giving a :)

-4

Step-by-step explanation:

so first off, we evaluate this whole mess.

(4+l-12l/6)^2 / -9

then, we divide it.

(4+12/6)^2 / -9

now, we calculate it.

(4+2)^2 / -9

then, we evaluate it.

6^2 / -9

we then reduce the fraction.

36 / -9

solution: -4

50

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

the answers might not be correct use at own risk
