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

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

what

7/2

(decimal: 3.5)
