Answer:
80 + 18i
Step-by-step explanation:
i² = -1
x = i + 9
x² = (i + 9)²
Applying; (a + b)² = a² + 2ab + b² concept,
x² = i² + 18i + 81
We know that i² = -1
So x² = -1 + 18i + 81
x² = 81 - 1 + 18i = 80 + 18i

Answer:
A) A = 180 in
B) V = 144 in³
Step-by-step explanation:
A = 2 ( wl + hl + wh)
A = 2 (3 × 8) + (6 × 8) + (3 × 6)
A = 2 [(24) + (48) + (18)]
A = 2 × (90)
A = 180 in
V = w × h × l
V = 3 × 6 × 8
V = 144 in³
