Na aula de matemática o professor anotou na lousa : A=-2,C=3 e B=1,qual das equações abaixo corresponde a essa anotação? a)2x^2-x+1=0
b)3x+1=2x^2
c)X+3=2x^2
d)-2x^2=x+3

Por favor me ajudem preciso da resposta com o cálculo e a explicação

Ahas the coordinates (–4, 3) and b has the coordinates (4, 4). if do,1/2(x, y) is a dilation of △abc, what is true about the image △a'b'c'? check all that apply. ab is parallel to a'b'. do,1/2(x, y) = the distance from a' to the origin is half the distance from a to the origin. the vertices of the image are farther from the origin than those of the pre-image. a'b' is greater than ab.

With this one. will mark brainliest
