next number would be 89, because you add the number before to get the next,
8 + 5 = 13 + 8 = 21 + 13 = 34 + 21 = 34 + 21 = 55 + 34 = 89
final answer: 89

Step-by-step explanation:
plug 40 into each equation for x
50+12(40)
simplify
50+480
simplify
530
10+15(40)
simplify
10+600
610
now subtract 530 from 610
610-530
80
Answer:
408 in²
Step-by-step explanation:
A rectangular prism has 6 rectangular faces.
Opposite faces are congruent
2 faces at (6 × 9) = 2 × 54 = 108 in²
2 faces at (9 × 10) = 2 × 90 = 180 in²
2 faces at (6 × 10) = 2 × 60 = 120 in²
surface area = 108 + 180 + 120 = 408 in²
