Answer: A and c
Step-by-step explanation: because they are the only ones that have p,x,m and not just seperate.
The answer is A) The student failed to properly apply the distributive property.
--------------------------------------------------
Define length and width
--------------------------------------------------
Let x be the width
width = x
Length = 2x + 4
--------------------------------------------------
Formula
--------------------------------------------------
Perimeter = 2(length + width)
--------------------------------------------------
Find Length and width
--------------------------------------------------
62 = 2(2x + 4 + x)
62 = 2(3x + 4) <em> ← combine like terms </em>
62 = 6x + 8 <em>← remove bracket </em>
62 - 8 = 6x <em>← minus 8 on both sides </em>
6x = 54 <em> ← swap sides </em>
x = 54 ÷ 6 <em>← divide by 6 on both sides</em>
<em>x = 9 m</em>
--------------------------------------------------
Find Length and Width
--------------------------------------------------
Width = x = 9 m
Length = 2x + 4 = 2(9) + 4 = 22 m
--------------------------------------------------
Answer: Length = 22m
--------------------------------------------------
