Answer:
The answer is 32
Explanation:
3( 2c + d) - 4( c - d) + d²
when c = 1 and d = 3
Substitute the values of c and d into the above expression and solve
We have
3 [ 2(1) + 3 ] - 4 ( 1 - 3) + 3²
Solve the terms in the bracket first
➢ 3( 2 + 3) - 4( - 2) + 9
➢ 3( 5) + 8 + 9
Simplify
➢ 15 + 8 + 9
➢ 15 + 17
We have the final answer as
32
