-- 24 is a factor of itself and every multiple of 24 .
There are an infinite number of them.
-- 24 is a multiple of each of its factors.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24 .
1.) C is the correct choice
4.) B is the correct choice
3x-2x^2+7-3x^2
=3x-2x^2-3x^2+7
=3x-5x^2+7
=-5x^2+3x+7 that’s how it’s solved and that’s the answer as well. Come back for help
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
