Multiply each term in the first set of parentheses by each term in the second set, then combine like terms.

7x x 3x^2 = 21x^3

7x x -4x = -28x^2

7x x 5 + 35x

-6 x 3x^2 = -18x ^2

-6 x -4x = 24x

-6 x 5 = -30

Combine like terms to get:

21x^3 - 46x^2 + 59x - 30

If the 13th and 38th terms of an arithmetic sequence are -53 and -128,

love history [14]

9514 1404 393

Answer:

-2018

Step-by-step explanation:

The n-th term is ...

an = a1 +d(n -1)

So, the given terms are ...

-53 = a1 +12d

-128 = a1 +37d

Subtracting the first from the second gives ...

(a1 +37d) -(a1 +12d) = (-128) -(-53)

25d = -75

d = -3

The 668th term will be ...

a668 = a1 +d(668 -1) = a1 +667d = (a1 +37d) +630d

a668 = -128 +630(-3) = -128 -1890 . . . . substitute for a38

a668 = -2018
