What’s -3 + 6k + 11k - 10
-9y + 5x -y -13x
an -5x + 6x - 9x + 5xy ? (combining like terms)

Step-by-step explanation:

-3+6k+11k-10-9y+5x-y-13x

-13+17k-10y-8x

-5x+6x-9x+5xy

-8x+5xy

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

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)
