1) Observe as equações a seguir e identifique os coeficientes de cada equação: a) 5x² + 4x + 2 = 0 b) –x² + 3x + 4 = 0 c) x² - 4x + √7 = 0 d) x² + 8 = 0

La respuesta esta abajo

Step-by-step explanation:

Un coeficiente es un número o símbolo multiplicado por una variable o una cantidad desconocida en un término algebraico, polinomio, una serie o cualquier expresión.

a) 5x² + 4x + 2 = 0

El coeficiente de x² = 5, el coeficiente de x = 4

b) –x² + 3x + 4 = 0

El coeficiente de x² = -1, el coeficiente de x = 3

c) x² - 4x + √7 = 0

El coeficiente de x² = 1, el coeficiente de x = -4

d) x² + 8 = 0

El coeficiente de x² = 1, el coeficiente de x = 0

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
