Se considera piramida patrulatera regulata VABCD, iar M si N mijloacele muchiilor [VD] si [VB]. Stabiliti care este dreapta de intersectie a planelor : a) (VAC) si (ABD) b) (VAB) si (VDC) c) (AMN) si (VBD d) (AMB) si (CND)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
