Answer:
3(2c + d) - 4(c - d) + d² = 32
Explanation:
Now we have to,
→ Simplify the given expression.
We have to use,
→ d = 3
→ c = 1
The given expression is,
→ 3(2c + d) - 4(c - d) + d²
Let's simplify the expression,
→ 3(2c + d) - 4(c - d) + d²
→ 3(2(1) + 3) - 4(1 - 3) + 3²
→ 3(2 + 3) - 4(-2) + 9
→ 3(5) + 8 + 9
→ 15 + 17
→ 32 => {final answer}
Therefore, the answer is 32.
