Answer:

3C + 3D = 12x² -12x + 30

Step-by-step explanation:

Given

C = x² + 7

D = 3x² - 4x + 3

To determine

3C + 3D

The expression is given by

3C + 3D

substituting C = x² + 7 and D = 3x² - 4x + 3

= 3(x² + 7) + 3(3x² - 4x + 3)

= 3x² + 21 + 9x² - 12x + 9

= 12x² -12x + 30

Thus, the expression in standard form is:

3C + 3D = 12x² -12x + 30
