P of a rectangle= 2l + 2w
P = 2(48) + 2(20)
P= 96 + 40
P= 136m
The length of the rectangle is 136 meters.
I hope that helped.
Y=(3x-5)/4
To find the inverse, flip x and y and solve for y.
x=(3y-5)/4
4x=3y-5
4x+5=3y
(4x+5)/3=y
Final answer: B
I think the answer is the first one, because it needs to be negative. <span />
