RQPO is a trapezoid. What is the value of x?

2

63°

(6x + 9°

R

18°

Step-by-step explanation:

Find the diagram attached

From the diagram, since the opposite side are parallel, the sum of the adjacent angle is 180 degrees

From the diagram, m<RQP + m<QPO = 180

Given

m<RQP = 6x+9

m<QPO = 63

Substitute

6x+9+63 = 180

6x + 72 = 180

6x = 180 - 72

6x = 108

x = 108/6

x = 18 degrees

Hence the value of x is 18°

x = -2

y = 848

step-by-step explanation:

plug in the numbers

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.
