Answer:
Width = 9 inches , length = 12 inches.
Step-by-step explanation:
Let the width = x inches, then its length x+3 inches.
Perimeter = 2x + 2(x + 3) inches so
2x + 2(x + 3) = 42
4x + 6 = 42
4x = 36
x = 36/4 = 9
So the width is 9 in and length = 9 + 3 = 12 inches.
You are correct.

Answer:
No
Step-by-step explanation:
[5+3x] is an expression that cannot be added because 5 is a natural interger but 3x is an unknown
and therefore it cannot be divided by 2 to get 4
Better example :
if the question will give 4x , then
it should be [5x+3x]/2 = 8x/2 = 4x
it's obvious from the example I gave that 8x can be divided by 2 to give 4x
