Let's approach this problem by slowly eliminating choices.
First consider the keyword "at most" and "no more than". This means that the inequality should be less than or equal to the constant value stated. This will automatically eliminate two choices with the greater than symbol favoring the variables - choices A and D.
Next we associate the right constants to the right coefficients of variables. The two kinds of weight the truck transports are 30 and 65 lbs, and we know that this should not exceed 3,800 lbs. This is therefore our first inequality. The other inequality is for the volume. The combinations of the two volumes 4 and 9 cubic feet should not exceed 400 cubic feet when transported.
If you try to construct the inequality and miss it among the choices, don't worry! Let's try doing some simplifications first and see if it matches either B or C.
After simplification you can get
from dividing the equation by 5 and 
for leaving it as it is.
Looking carefully, we can see that this is equivalent to option B.

Answer:
16 x units
Step-by-step explanation:
Perimeter of a original square= 8 x units
Perimeter of a square= 4× side
Side of a square =
Side of a square =
Side of a square= 2 x units
since four square are joined together to form a single square
So each side of a bigger square= 4 x units
Perimeter of a new bigger square= 4 × 4 x units
Perimeter of a new bigger square= 16 x units
Hence, the correct answer is 16 x units
