The figure shown is a trapezoid. Which expression represents the area of the trapezoid? A: 3x+3
B: 3x^2+6x+3
C: 3x^2+3x+6
D: 6x^2+6x

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

step-by-step explanation:

i googled it and this is what i got i don't know how it is. sorry.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
