The answer is c!!!!!!!!!!!!!!
Answer:
a²(b² - 2b) = a²b² - 2a²b
- a²(b² - 2b) is odd but -2a²b is the even number
=> a²b² must be the odd (because an odd number minus an even number equals an odd number)
=> a and b are odd (proven)
Answer:
136 units²
Step-by-step explanation:
The surface area (SA) is calculated as
SA = area of base + area of 2 congruent sloping faces + area of 2 triangular ends
area of base = 6 × 7 = 42 units²
area of sloping faces = 2 (7 × 5) = 2 × 35 = 70 units²
area of triangular faces = 2 × × 6 × 4 = 6 × 4 = 24 units²
SA = 42 + 70 + 24 = 136 units²
Answer:
About 30%
Step-by-step explanation:
1) figure out how many people didn't respond: 1334-931=403
2) divide small number by big number(nearest tenth): 403/1334=.30
3) move decimal to the right two times: 20%
