Question

responda a 12 e a 13 para mim,e para hj​

Answer 1

Resposta:

12)

a)

P(x) = A = b*h

P(x) = A = (7y + 5 ) * (y - 2)

P(x) = A = 7y² - 14y + 5y - 10

P(x) = A = 7y² - 9y - 10

b)

P(x) = A = b*h

P(x) = A = (8x + 3 ) * (4x + 1)

P(x) = A = 32x² + 8x + 12x + 3

P(x) = A = 32x² + 20x  + 3

13)

P(x) = A = b*h

P(x) = A = (x - 2y ) * (2x - 3y)

P(x) = A = 2x² - 3xy -4xy + 6y²

P(x) = A = 2x² - 7xy + 6y²
