Step-by-step explanation:

The dimensions of the gold bar is 16 centimeters by 2.5 centimeters by 5 centimeters.

The density of the gold bar is 19.3 grams per cubic centimeter.

We know the formula,

Volume = 16×2.5×5 = 200 cubic centimeters.

Substituting the known values in the above formula, we get

Hence, mass of the gold bar is 3860 grams.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
