Mark you Brainliest If x1, x2, x3, ..., x8 are the roots of the eighth-degree polynomial, 2x^8+bx^7+cx^6+dx^5+ex^4+fx^3+gx^2+ hx+m,

find the value of b when:

x1 + x2 + x3 = 6

x2 + x3 + x4 = 18

x3 + x4 + x5 = 9

x4 + x5 + x6 = −3

x5 + x6 + x7 = −9

x6 + x7 + x8 = −6

x7 + x8 + x1 = −2

x8 + x1 + x2 = 2

answer: (1,3) (3,-1) (5,-5) ?

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

52 \43 i don't know this i tried

the anwser is x< -17/2
