I. Elena began to solve this equation: 12x + 6(4x + 3)
= 2(6x +4-2)
3
12x + 6(4x + 3) = 3(2(6x + 4) - 2)
12x + 6(4x + 2) = 6(6x + 4) - 6
12x + 24x + 18 = 36x + 24 - 6
When she got to the last line, she stopped and said the equation is true for all values of x (infinite solutions).
low could Elena tell?
A. The variable terms and constant terms are different
B. The variable terms are the same, but the constant terms are different
C. The variable terms are different, but the constant terms are the same
D. The variable terms and constant terms are the same

answer: options

step-by-step explanation:

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best

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)
