Marie was trying to show her friend why -3 × -8 equals a positive product. This is what she wrote:-3 × 0 = 0-3 × (?) = 0-3(8) + -3(-8) = 0-24 + 24 = 0What should Marie write in place of the question mark? A. 8 + 8 B. -8 + (-8) C. 8 + (-8) D. -8 + 0

answer: a

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)
