Answer:
3 5/9 or 32/9
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The opposite faces are congruent, that is the surface area (SA) is
SA = top/ bottom + 2 sides + front/ back
= (3 × 2) + (3 × 2) + (2 × 5) + (2 × 5)+ (3 × 5) + (3 × 5)
= 6 + 6 + 10 + 10 + 15 + 15
Since it is odd, 4, 6 and 10 cannot be divisors.
5 cannot be a divisor since when you count by 5's you get numbers ending in 5 or 0
(5,10,15,20, etc)
9 cannot be a divisor since 9 x 6 = 54 and 9 sx 7 = 63
None of your answers will work with 57.
3 will work even though you did not list it. 5+7 = 12 and 1+2 = 3. If the sum of the digits = 3, 6 or 9, the number is divisible by 3.
45 is divisible by 3 (4+5=9)
78 is divisible by 3 (7+8=15 and 1+5 = 6)
-4.7
-8.1 - -3.4= -4.7
-4.7+-3.4=-8.1
