Geometry: these are all true or false questions
1.) the diagonals of a rectangle are perpendicular.
2.) the opposite angles of a rhombus are equal.
3.) the diagonals of a rhombus are perpendicular.
4.) every quadrilateral is a parallelogram.
5.) no parallelogram is a rhombus.
6.) every parallelogram is a rhombus.
7.) every square is a parallelogram.
8.) every square is a rectangle.
9.) every square is a rhombus.

the equivalent expression are always the hardest ones but you look at the gcf also

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.
