Question

The expression a[b+(c−d)]

is equivalent to:

A. ab+ac−ad

B. ab+ac+ad

C. ab+ac−d

D. ab+c+d

E. ab+c−d

Answer 1

A

Explanation:

When you distribute values, 'a' while be multiplied by everything. since there is a plus sign in front of the 'b' then that will not be distributed. so an 'ab' will add the an 'ac' but an 'ad' is still going to subtract away from the equation.
