\frac{(2n+3)^{2}-(2n+1)^{2}}{6n+6} \\ \\ =\frac{(4n^{2}+12n+9)-(4n^{2}+4n+1)}{6n+6} \\ \\ =\frac{4n^{2}+12n+9-4n^{2}-4n-1}{6n+6} \\ \\ =\frac{8n+8}{6n+6} \\ \\ =\frac{4(2n+2)}{3(2n+2)} \\ \\ =\frac{4}{3} \\ \\ \therefore \boxed{a=4, b=3}

Write the first 4 terms of the arithmetic sequence With first term 37 and common difference 9
alexandr402 [8]

Answers:

first term = 37

second term = 46

third term = 55

fourth term = 64

==========================================

Explanation:

Start at 37. Add 9 to this term to get the second term. Add 9 to that result to get the next term, and so on.

first term = 37

second term = 37+9 = 46

third term = 46+9 = 55

fourth term = 55+9 = 64

-----------

The nth term formula is

a(n) = 9n+28

It can be found by plugging a = 37 and d = 9 into the general form

a(n) = a + d*(n-1)

(-w-6)/(w^2+4w-12), how do i write this into simplest form?
PIT_PIT [208]
First factorise the top = -(w+6)
The first factorise the bottom: (w^2 + 4w -12) = (w+6) (w-2)
Therefore the two (w+6) cancels out and you are left with -1 / w-2
