Answer: the answer should be x=-2
Answer:
1.) Yes
2.) Yes
Step-by-step explanation:
Given that
n = k(k + 7)
If k is a positive integer and n = k(k + 7), is n divisible by 6 ?
(1) k is odd. Yes.
Let assume that k = 3
Then, n = 3(3 + 7)
n = 3 × 10
n = 30.
30 is divisible by 6.
(2) When k is divided by 3, the remainder is 2. That is,
Let k = 5
Then,
5/3 = 1 remainder 2
Substitute k into the equation
n = k(k + 7)
n = 5(5 + 7)
n = 5 × 12
n = 60
And 60 is divisible by 6.
Therefore, the answer to both questions is Yes.
Senator Smith's percentage rating must increase by 13% in other to undo the previous decreases.
Initial rating = 62%
April rating = 57%
May rating = 57% - 8% = 49%
Final rating after decrease = May rating = 49%
In other to return to initial rating :
Initial rating - Final rating
62% - 49% = 13%
Hence, in other to undo the decrease in April and May rating, Senator Smith's percentage rating must increase by 13%
