What is the correct order of operations for simplifying the expression ? square the binomial (x + 3),
a) distribute the negative to the binomial (x2 + 9), simplify the dividend, and then divide divide, square the binomial (x + 3),
b) distribute the negative to the binomial (x2 + 9), and then simplify the dividend square the binomial (x + 3), divide,
c) distribute the negative to the binomial (x2 + 9), and then simplify the dividend square the binomial (x + 3),
d) distribute the negative to the binomial (x2 + 9), divide, and then simplify the dividend

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)

step-by-step explanation:

the answer to this is 4340

hope this if needed hmu
