Arectangle has sides measuring (6x + 4) units and (2x + 11) units.

part a: what is the expression that represents the area of the rectangle? show your work to receive full credit. (4 points)

part b: what are the degree and classification of the expression obtained in part a? (3 points)

part c: how does part a demonstrate the closure property for polynomials? (3 points)

the answer is 489

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
