How important are the "special features" of a polynomial graph? When would you need to find all of the precise values of special features of the graph of a polynomial function? When would it be okay to estimate these values? Give examples in context, if possible.

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

happy to

$15 each

step-by-step explanation:

$45/3 children= $15 each

i think the answer is b

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
