<span>Twice the sum of a number and 3 = 2(n + 3)
</span><span>three times the difference of the number and 3 = 3(n - 3)
so
</span><span>Twice the sum of a number and 3 is equal to three times the difference of the number and 3:
</span>2(n + 3) = 3(n - 3)
2n + 6 = 3n - 9
n = 15
answer
2(n + 3) = 3(n - 3)
n = 15
Since it turns downwards (the shape on an "n", it is a maximum point)
Maximum point occurs at (-2, 1)
Answer: (B) (-2, 1) maximum
76.
If the number after the decimal is below five, you round down. If the number is above five, you round up. 76 is your answer.
There is no solution because x is incorrect.
x should be 32
