What are the solutions of this quadratic equation? x2 + 8x + 3 = 0

-4 + √13 ; -4 - √13

Step-by-step explanation:

x² + 8x + 3 = 0

(x² + 2(x)(4) + 4²) - 4² + 3 = 0

(x + 4)² -16 + 3 = 0

(x + 4)² = 13

x + 4 = √13

x = -4 + √13

x + 4 = -√13

x = -4 - √13

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
