I need help please & thank you

Answer 1

3(2c+d)-4(c-d)+d^2

c=1 , d=3

Use the substitution method

3(2*1+3)-4(1-3)+3^2

Multiply the brackets

3(2+3)-4+12+9

6+9-4+12+9

15-4+12+9

11+21

=32

Answer: 32

Answer 2

Answer:

32

.

Step-by-step explanation:

3(2c + d) - 4(c - d) + d^2

Substitute c = 1 and d = 3:

3 * (2*1 + 3) - 4(1 - 3) + 3^2

= 3*5 - 4(-2) + 9

=  15 + 8 + 9

= 32.
