Find the student's error in solving the following
inequality
31 < -5x + 6
25 < -5x
-5 the student should have added 6 to both
sides instead of subtracting it.
the student divided 251–5 incorrectly.
the student should have switched the
direction of the inequality sign to get -5> x for
a final answer.

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
