Expand the expression. 2x^2(x + 3)(x–2) 2x3 + 2x2 – 12x 4x3 + 6x2 – 4x2 2x4 + 2x3 – 12x2

(A) is the correct option.

Step-by-step explanation:  We are given to expand the following expression :

To expand the given expression, we must multiply each term of every expression to each term of the other two expressions.

The expansion is as follows :

Thus, the required expended form is

Option (A) is CORRECT.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
