Answer:
Step-by-step explanation:
A. The student didn’t cube 2.
8x^3y^6
B. The student didn’t add 1/3+1/3 correctly to be 2/3
a^(2/3)
C. The student moved the coefficient 2 into the denominator which is incorrect.
2/(x^2)
He would finish around 2 hrs and 40 minutes
A = 4(187*230/2) + 230²
A = 4*21505 + 230²
A = 86 020 + 52 900
A = 138 920 m²
