Answer: 
Step-by-step explanation:
Given : Starks sculpture 30 cubed is a cube with sides 30 inches long.
We know that the volume of a cube is given by :-
Then , the volume of Starks sculpture 30 cubed will be :
Hence, the required volume =
4 x U(unit price) = $43.80
U = 43.80 / 4
U = 10.95$
7 x 10.95 = 76.65$
Let n = 1
then f(1) = 1^1 - 1 + 2 = 2 so it is true for n = 1
for the next number after n ( n+1) we have f(n+1) =
(n+1)^2 - (n+1) + 2
= n^2 + 2n + 1 - n - 1 + 2
= n^2 + n + 2
= n(n+1) + 2
Now n(n+1) must be divisible by 2 because either n is odd and n+1 is even OR n is even and n+1 is odd and odd & even always = an even number.
So the function is divisible by 2 for n+1 We have shown that its true for n = 1 Therefore it must be true for n = 1,2,3,4 ...
True for all positive integers
Answer:
x=14
Step-by-step explanation:
45 = 3 (x + 1)
Distribute the 3 to both terms in the parentheses
45 = 3x +3
Subtract 3 from each side
45-3 = 3x+3-3
42 = 3x
Divide each side by 3
42/3 = 3x/3
14 =x
