Can someone help me? factor the polynomial W(x) = x^3 + 3x^2 + 6x + 18
W(x) = 9x^3 – 9x^2 – x + 1
W(x) = 5x^3 + 15x^2 – x – 3
W(x) = x^5 + 2x^4 – 27x^2 – 54x
W(x) = x^4 – x^3 – 6x^2
W(x) = 2x^4 + x^3 – x^2
W(x) = 4x^4 – 12x^3 + 5x^2
W(x) = x^4 – 2x^3 – 3x^2

.

Step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
