Each leg of a 45 45 90 triangle has a length of 6 units what is the length of its hypotenuse? . a 6 units. b 12 units. c 3 square root over 2 units. d 6 square root over 2 units

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

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
