I NEED HELP PLS PLS PLS PLS The signal words _[blank A]_ indicate subtraction.

The signal words twice, double, and triple indicate _[blank B]_.

When a situation has more than one operation, be aware that you might have to use _[blank C]_ in the expression.

Parentheses tell you to do the operation inside them _[blank D]_.

Match each blank with the correct item that fills in that blank.

decreases by --> substraction

twice, double, triple --> multiplication

more than one operation --> parentheses?

do parentheses --> first

< 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)
