Answer:
It’s depends on how much of your grade the assignment was worth
Step-by-step explanation:
The expression to be simplified is: (9x^2 - 25) / (3x + 5)
We first factor the numerator: 9x^2 - 25 is a difference of two squares, (3x)^2 - (5)^2, so this can be factored into (3x + 5)(3x - 5).
Then the expression becomes (3x + 5)(3x - 5) / (3x+5), and the 3x + 5 term cancels out, leaving just 3x - 5 as the final answer.
The answers are:
the first term: 21
the fourth term: 22
the tenth term: 39
<span>A(n) = 12+(n - 1)(3)
n = 1
A(1) = 12 + (1 - 1)(3) = 12 + 0*3 = 12 + 0 = 12
n = 4
</span>A(4) = 12 + (4 - 1)(3) = 12 + 3*3 = 12 + 9 = 21
n = 10
A(10) = 12 + (10 - 1)(3) = 12 + 9*3 = 12 + 27 = 39
