Someone plz give me the answer for this. Btw I know if you add them all it would be A but there are 3 lines left then add them all. So basically just give me the answer plzzz I really need your help.

Option D. 37¼ ft

Step-by-step explanation:

The perimeter of the figure above can be obtained by adding all the lengths of each sides together. This can be obtained as follow:

The lengths of each sides are given below:

Top = 6¼ ft

Left = 9⅛ ft

Bottom = 9½ ft

Right = 7¾ ft

Top horizontal = 9½ – 6¼

= 19/2 – 25/4

= 13/4 ft

Top height = 9⅛ – 7¾

= 73/8 – 31/4

= 11/8 ft

Perimeter = 6¼ + 9⅛ + 9½ + 7¾ + 13/4 + 11/8

= 25/4 + 73/8 + 19/2 + 31/4 + 13/4 + 11/8

= 149/4

= 37¼ ft

Thus, the perimeter of figure is 37¼ ft

answer:

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
