What two polygons are directly below a parallelogram on the quadrilateral hierarchy? quadrilateral and kite
square and trapezoid
rhombus and rectangle
parallelogram and trapezoid

rhombus and rectangle

Step-by-step explanation:

In the quadrilateral hierarchy :

A quadrilateral is divided into a trapezium, kite and parallelogram

the polygon below the trapezium is the isosceles trapezium

the polygon below the parallelogram is the rhombus and rectangle

the polygon below the  kite is the rhombus

the polygon below the rhombus and the rectangle is the square

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

mrb

(a + b) (a^2 - a b + b^2)
