How to solve 3x^2+22x=-35 by factoring

Zepler [3.9K]

Answer:

x = -7/3 or -5

Step-by-step explanation:

3x^2 + 22x = -35

3x^2 + 22x + 35 = 0

(3x + 7) (x + 5) = 0

so for 3x+7:

3x+7 = 0

3x = -7

x = -7/3

So for x + 5:

x + 5 = 0

x = -5

Find the 75th term of the arithmetic sequence -1, 15, 31, ...−1,15,31,...

Readme [11.4K]

Answer:

1183

Step-by-step explanation:

Common difference:

d = 31 - 15 = 16

nth term:

$a_n = a_1 + (n - 1)d$

Here, $a_1 = -1$

$a_{75} = -1 + (75 - 1)(16)$

$a_{75} = 1183$
