Which of the following is equivalent to equivalent to –2(15 – 20d + 5c)?
A. –30 + 40d – 10c
B. –6 + 8d – 2c
C. –2c + 8d – 6
D. –2(3 – 4d + c)

After solving the given expression, the equivalent expression will be -30 +40c - 10c.

If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.

The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. A mathematical operation like reduction, addition, multiplication, or division is used to include terms in an expression.

As per the given information in the question,

-2(15 - 20d + 5c)

Now, multiply -2 by the values in the bracket,

Then, the equivalent expression will be,
