Question

Evaluate and simplify the expression when c=1 and d=3. 3(2c + d) - 4(c-d) + d2 = [?]​

Answer 1

The answer is 32

Explanation:

3( 2c + d) - 4( c - d) + d²

when

c = 1

d = 3

Substitute the values of c and d into the expression and solve

That's

3[ 2(1) + 3 ] - 4( 1 - 3) + 3²

= 3( 2 + 3) - 4( - 2) + 9

= 3(5) + 8 + 9

= 15 + 17

We have the final answer as

32

Hope this helps you
