(7n - 4)(n + 3)

3n and n = 4? 3n ( the four replaces the n 3(4) = 12 =======

4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True

3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1

-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4

-7n2 + 74n + 33 = -7n2 + 77n - 3n + 33 = -7n*(n - 11) - 3*(n - 11) = =(-7n - 3)*(n - 11) = -(7n +3)*(n - 11)

The nth term of this sequence is 3n + 4

(7n - 4)(n + 3)

3n and n = 4? 3n ( the four replaces the n 3(4) = 12 =======

3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6

When n = 4, 3n = 3*4 = 12

3n+2+3n+2=6n+4

3n^4 divided by 3n^3 = n

4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True

Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2

3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1

3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
