Length=2(x-1)
Width=5
Area=length*width = (2(x-1))(5) = (2x-2)(5) = 10x-10

His reasoning is illogical because whether or not an expression has a term that is being subtracted isn't relevant; technically there are an infinite amount of ways to represent a value. Plus you can just compute the expressions and see that they're equal:
6x-2x+4 = 4x+4
4(x-1) = 4x+4
30
The two expressions are equal because when you compute the expression 4(n+3)-(3+n) , you get 3n+9:
4(n+3)-(3+n) = 4n+12-3-n = 3n+9
31
The two expressions are equal because when you compute the expression 2(2n-1), you get 4n-2.
2(2n-1) = (2)(2n)+(2)(-1)=4n-2
32
5(g+14)=(5)(g)+(5)(14)=5g+70
The expressions aren't equal as 5(g+14) equates to 5g+70 and 5g+70≠5g+14.
All you have to do is 100 plus 10 is 110 plus if you need to understand it better you can use base ten blocks use one hundred block and 1 tens block is the same thing. 100 is in one block and 10 is in one tens block. Hope this helped you ( :
2L + 2w = 112 ---> L + w = 56 ---> w = 56- L
Area = L*w = L(56-L) = 735
56L - L^2 = 735
0 = L^2 - 56L + 735
0 = (L - 21)(L - 35)
