2(2x-1) + 2(3x)=4x-2+6x = 10x - 2 & not <span>=10x-1</span>
One side (l) = 2x-1
other side (w) = 3x
perimiter = all of the sides added together
perimiter = 2l + 2w
perimiter = 2(2x-1) + 2(3x)
2(2x) - 2(1) + 2(3x) = 4x - 2 + 6x
perimiter = 10x - 2
<em>The previous statement is incorrect because the student did not distribute the 2 onto the -1.</em>
