A developmentalist is studying the relationship between parental physical punishment (e. g., hitting, spanking) and first graders' aggression. Her plan is to individually watch each parent interact with a child at home, and then observe that child's behavior at school. Name the type of measurement strategy this researcher is using, and spell out its advantages and disadvantages.

castigo es suficientemente duro, puede producir en el niño efectos tales como esconderse de quien lo castigó, mentir y rehuir el reconocimiento de su responsabilidad por temor al desquite. 5 En otras palabras, puede destruir el sentido de apertura y confianza en la relación padre–hijo, o alterar el

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7

are there actual statements because if not my answer would be: that using the five senses the author can create a sense of worth in an object to appeal to the reader and create meaning.
