Which student correctly translated the phrase “twice the sum of a number cubed and nine” and evaluated it for r = 3? Antonio's work. 2 (r cubed + 9) = 2 (3 cubed + 9) = 2 (9 + 9) = 2 (18) = 36.
Jessica's work. 2 (r cubed + 9) = 2 (3 cubed + 9) = 2 (27 + 9) = 2 (36) = 72.
Maria's work. 2 + r cubed + 9 = 2 + 3 cubed + 9 = 2 + 27 + 9 = 29 + 9 = 38.
Mark's work. 2 + 3 r + 9 = 2 + 3 (3) + 9 = 2 + 9 + 9 = 11 + 9 = 20.

Jessica correctly translated the phrase “twice the sum of a number cubed and nine” and evaluated it for r = 3

Step-by-step explanation:

Antonio didn't cube r after plugging it in for 3.

Maria didn't put multiply r³ + 9 by 2. She added it instead.

Mark did the same thing as Maria except he didn't cube r at all. He put 3 as the coefficient.

B. Jessica Work is correct.
