(4*a)*2
lets give a a number: a = 3 so (4*3)*2 = 12*2 = 24
lets try the options:
A) 4 *(3*2) = 4*6 = 24 = the same
B) 4*2*3*2 = 8*3*2 = 24*2 = 48 = different
C) 8*3 = 24 = same
D) 4*2+3*2 = 8 +6 = 14 = different
E) 2*(4*3) = 2*12 = 24 = same
so A, C & E would be the equivalent.

Answer: 62/3
Step-by-step explanation:
area = length * width
area = 8/3 * 31/4
area = 62/3
The word 'difference' indicates the use of subtraction in a Mathematical sum
The error is that the sum could be 15 - 5y instead of 5y - 15
A subtraction sum does not have the commutative properties, meaning that we cannot do the sum in any order.
A sum 15 - 5y will give a different result with the sum 5y - 15 for the same value of y.
