PLEASE ANSWER ASAP WILL GIVE BRAINLIST

X= -5/3

Step-by-step explanation:

I am sure that this answer is correct I have used an Algebra calculator against my work and I have gotten this answer both times. Please mark Brainliest.

f = -5 / 3

Step-by-step explanation:

Assuming you want to solve for f:

Solve algebraically.

First, isolate the variable:

-3/4 x f = 5/4

f = (5/4) / (-3/4)

Next, simplify:

f = - 20 / 12

f = -5 / 3

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
