Which of the following are possible rational roots of the polynomial function

The correct options are:

          A.  

          B.  

          D.  

Rational Root theorem--

For any polynomial function of the type:

where are integers.

The rational roots are of type p/q where p is the factor of and q is the factor of

Here p is a factor of 7.

i.e.p could take value 1,-1, 7 and -7.

and q is a factor of 2.

i.e. q could take value 1,-1,2 and -2.

The possible rational roots are given by:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
