Answer:
if you see three consecutive numbers you can figure out that at least one of them is divisible by 6
Step-by-step explanation:
you can use mathematical induction by proving it mathematically. for a number to be divisible by 6, it should be divisible by 2. Since all are even numbers the number will be divisible by 2.

Answer:
$28.14
Step-by-step explanation:
The area of a container will be the sum of the base area and the lateral area. The relevant formulas are ...
A = πr^2 . . . . . . . . area of the circular base with radius r
A = 2πrh . . . . . . . area of the side of the container
The sum of the two areas is ...
Atot = πr^2 +2πrh = πr(r +2h) = π(7/2 cm)(7/2 cm +2·21 cm) = (π/4)(7)(91) cm^2
Atot = 159.25π cm^2 = 0.015925π m^2 . . . . metal area per container
__
Then 125 containers will have an area of ...
Aall = (125)(0.015925π m^2) = 1.990625π m^2 ≈ 6.25373 m^2
The price of this amount of sheet metal will be ...
(6.25373 m^2)($4.50 /m^2) = $28.14 . . . cost of 125 containers

<em>Additional comment</em>
1 cm = 0.01 m, so (1 cm)^2 = (0.01 m)^2 = 0.0001 m^2
Answer:
So it looks like the given zeros are 2i and -3. We have to work backwards.
x = -3 and x = 2i
For -3, we know that out factored form before would have been x + 3
For 2i, that means we took the square root of negative number because it is imaginary. So that means out factored for x2 + 4
So if we put these together:
(x2 + 4)(x + 3) = x3 + 3x2 + 4x + 12

Step-by-step explanation:
More than means add
quotien t is divide
68+(x/54)=72
subtract 68
x/54=4
multiply both sides by 54
x=216
