What do a triangle and a quadrilateral have in common? a. both have three sides. b. both are polygons. c. neither end with "-gon." d. both have vertices. (there can be more that one answer)

we know that

polygons is a plane figure with at least three straight sides and angles, and typically five or more.

so,

both triangle and quadrilaterals are polygons

so,

option-B and option-DAnswer

B.Both are polygons.

D.Both have vertices.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
