Answer:

3x³ + 23x² + 63x + 55

Step-by-step explanation:

Given

(3x + 5)(x² + 6x + 11)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis

= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms

= 3x³ + 23x² + 63x + 55

Calculate S5 for the sequence defined by {an}={1+5/2n}<br><br> 13.5<br> 23<br> 40<br> 42.5
goldfiish [28.3K]
This is an arithmetic series, where S5 means the sum of the first 5 numbers in the series. The general formula is:

Sn = (n/2)(a1 + an)

So,
a1 = 1 + 5/2(1) = 3.5
a5 = 1 + 5/2(5) = 1.5

S5 = (5/2)(3.5+1.5)
S5 = 12.5

<em>The answer should be 12.5</em>
