Are the two expressions equivalent when x=20?

8 (12x+4)

96x+32

If x = 20, then

8 (12 • 20 + 4) = 1,952, and

96 • 20 + 32 = 1.952.

Both expressions are equivalent due to when applying the distributive property to the first equation '8 (12x + 4) ', you would multiply both 12 and 4 by 8. This would leave you with the equation 96x + 32.
