The work of a student to find the dimensions of a rectangle of area 6 + 8x and width 2 is shown below:
Step 1: 6 + 8x
Step 2: 2(4) + 2(6x)
Step 3: 2(4 + 6x)
Step 4: Dimensions of the rectangle are 2 and 4 + 6x
In which step did the student first make an error and what is the correct step?
Step 3; 2 + (4 + 6x) Step 3; 2 + (4 ⋅ 6x) Step 2; 2(4) + 2(4x) Step 2; 2(3) + 2(4x)

Best ResponseYou've already chosen the best response.1whoa... please do not mass tag. It's a form of spam on OS and anyway A = L X W area of the rectangle = length x width

Best ResponseYou've already chosen the best response.1so given area 6+8x width 2 6+8x =2L

Best ResponseYou've already chosen the best response.1hmmm... perimeter is P=2L+2W but it's not asking that..

Best ResponseYou've already chosen the best response.1area > 6+8x width > 2 length > ? area = width x length 6+8x=2L and supposedly to get length by itself we have to divide 2 3+4x=L

Best ResponseYou've already chosen the best response.1so 6+8x = 2(3+4x) ok the width is 2 and the length is 3+4x. student messed up really early.

Best ResponseYou've already chosen the best response.1looks like she is going backwards step 1 we have 6+8x then split these two numbers up 2(3)+2(4x) the 2 is yanked out 2(3+4x) yay! 6x+8 = 2(3+4x) 6x+8=6+8x

Best ResponseYou've already chosen the best response.1Step 2; 2(3) + 2(4x) < this is the correct one. It took a while because I haven't done this in years, but with patience we got what we need ^^

Best ResponseYou've already chosen the best response.1an that part works because I was using A =WL 6+8x=2L and solved for L which was 3+4x=L so by looking at her work carefully I see that she did it differently by not using the formula A =L X W so she split 6 and 8 and factored out a 2 but in her original step 2 she wrote the wrong number

Best ResponseYou've already chosen the best response.0so step 2 was the wrong one

Best ResponseYou've already chosen the best response.1oh yeah we can prove that with ease given that A = 6x+8 and width 2 on her step 2 she had Step 2: 2(4) + 2(6x) which doesn't make sense that 8+12x which is the wrong area

Best ResponseYou've already chosen the best response.0Step 2; 2(4) + 2(4x) Step 2; 2(3) + 2(4x) which one is right

Best ResponseYou've already chosen the best response.1distribute the 2 on 2(4)+2(4x) we got the wrong number with x again 8+8x we were NOT given that

Best ResponseYou've already chosen the best response.12(3) + 2(4x) that's 6+8x which is the area we were given in the first place

Best ResponseYou've already chosen the best response.1but recommendation to student use the formula A = L X W it's easier
