A = L * W
L = 3x + 5
W = x - 2
A = (3x + 5)(x - 2)
A = 3x(x - 2) + 5(x - 2)
A = 3x^2 - 6x + 5x - 10
A = 3x^2 - x - 10 <====
.12×10^5
... i got this by taking the first number 8 and then counting the places behind the 8 which would be 5 so than you move the decimal place by 5 so you get 8.12 then you show theirs 5 places behind the 8 by adding the 10^5 so you get 8.12×105
Answer:
I gotchu fam!
Step-by-step explanation:
4. Surface area = 605.76
Lateral = 9.8
5. Surface area = 352.8
Lateral = 241.5
6. Surface area = 134125.74343434433443
Lateral = 5444442.443
