This is for middle school for my grand daughter. please help.
1. a kite in the shape of a rhombus has diagonals that are 25 in long and 15 in long. what is the area of the kite?

2. the seat of a bench is in the shape of a trapezoid with the bases of 6 feet and 5 feet and a height of 1.5 feet. what is the area of the seat?

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

well what did you do it matters what you did : )

step-by-step explanation:

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)

you,

mrb

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