Решите уравнения: x^2+3x/2+x-3x^2/8=2x

(х^2)*8+(3х/2)*4+х*8-(3х^2/8)*1=2х*8 8х^2+12х+8х-3х^2=18х 5х^2+2х=0 х(5х+2)=0 х=0 либо 5х+2=0 5х=2 х=5/2=2,5 х={0; 2,5}

In the first picture, the girl is listening to music and from her face, we can understand that she is enjoying it.

Then, in the second picture, the boy is drawing a picture with colored pencils.

In the third, the group of kids is doing a piece of art. The boy with brown hair is drawing a picture, while a girl with black hair is doing pottery. (По картинке я не понял что делают другие)

In the last picture, the kids are playing in the band. We can see that the first boy in a yellow T-shirt is singing a song while his friends are playing on different instruments.

X²-6x+9≤0 (x-3)²≤0 y=(x-3)² - парабола с центром в точке (3; 0).                 она касается оси ох и не принимает отрицательных значений,                   т.к. её оси направлены вверх.                    однако, её значение может быть равно нулю при х=3                   ((х-3)²=0, х-3=0,  х=3) ответ: х=3
