Arectangle has sides measuring (4x + 5) units and (3x + 10) 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)

A =

Step-by-step explanation:

b = 3x+10

h = 4x+5

A = bh

A = (3x+10)(4x+5)

A =

A =

It is a second degree equation, since the major exponent is 2.

In the multiplication of polynomials, it is necessary to consider their exponents, because these are added by passing the same variable, and they must always be integers.

12x2+55x+50

Explanation:

the area of a rectangle is: A=length . width

(4x+5)⋅(3x+10)

=12x2+40x+15x+50

=12x2+55x+50

Step-by-step explanation:

what does x eaqual

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
