Answer:

Step-by-step explanation:-227 is in The sequence

13,7,1,-5,-11,.....

First term=a=13

Common difference=d=7-13=-6

Checking if -227 is in The sequence

using the formula

Tn=a+dx(n-1)

-227=13+(-6)x(n-1)

-227=13-6n+6

collect like terms

6n=13+6+227

6n=246

Divide both sides by 6

6n/6=246/6

n=41

Therefore -227 is the 41ist term Of The sequence

If A > B and C > D, then A + C > B + D.

steposvetlana [31]

The answer is Always true. because A is greater than B so put it this way if A=2 and B =1 then 2>1 same goes for C>D so if A+C would have to be greater than B+D for instance 2+2>1+1 or 4>2 so
<span>If A>B and C>D, then A+C>B+D Always true.

Find the product of 2x^4(4x^2 + 3x + 1).

lianna [129]

We want to find the product:

$\displaystyle{ 2x^4\cdot(4x^2 + 3x + 1)$ .

By the $\text{Distributive property}$ , we distribute $2x^4$ over each of the three terms inside the parenthesis:

$\displaystyle{ 2x^4\cdot(4x^2 + 3x + 1)=2x^4\cdot4x^2+2x^4\cdot3x+2x^4\cdot1$ .

Multiplying the coefficients, and adding the exponents we get:

$8x^6+6x^5+2x^4$ .

Answer: $8x^6+6x^5+2x^4$ .
