Question

ayudenme porfavor, lo necesito!​

Answer 1

a) -10x^2 - 35x + 75

b) Perímetro = 2(a) + 2(b)

44 cm = 2 (-2x + 3) + 2 (5x + 25)

44 cm = (-4x + 6) + (10x + 50)

44 cm = - 4x + 10x + 6 + 50

44 cm = 6x + 56

44 cm - 56 = 6x

-12 cm = 6x

-12 cm ÷ 6 = x

-2 = x

c) -2(-2) + 3 = 4 + 3 = 7 cm

5(-2) + 25 = - 10 + 25 = 15 cm
