X^2 + 3x - 10 = 0

2x + 3x - 10 = 0

2x + 3x = 5x

5x -10 = 0

+10 +10

5x = 10

5x/5 = 10/5

X = 2


Checking: 2^2 + 3(2) - 10 = 0

4 + 3(2) - 10 = 0

4 + 6 - 10 = 0

10 - 10 = 0

0 = 0

What is the sum of the arithmetic series
docker41 [41]

Answer:

S_ {12} = 192

Step-by-step explanation:

The nth term of the given arithmetic sequence is

U_n = 3 + 2n

The first term of this series is:

U_1 = 3 + 2(1) = 5

The last term of this series is when

n = 12

U_ {12}= 3 + 2(12)

U_ {12}= 3 + 24 = 27

The sum of the first n terms of an arithmetic series when the first an last term is known is given by:

S_n =  \frac{n}{2}(a + l)

Where a=5 is the first term and l=27 is the last term.

S_ {12} =  \frac{12}{2}(5 + 27)

S_ {12} =6(32) =19 2
