PLZ HELP

I am not to sure on this answer either:(

A rectangle 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. (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)

Part A:

To find the area of a rectangle you want to take length times width

(2x+11)(6x+4) You want to solve by using the FOIL method

First, Outer, Inner, Last

First terms 2x*6x=12x^2, when you multiply numbers with exponents you want to add, which is how we got it to squared

Outer terms~ 2x*4=8x, we take out two outer terms and times them by each other

Inner terms~ 11*6x=66x, we take our inner two terms and times them to each other

Last terms~ 11*4=44, we take the last two terms times each other

That now leaves us with

12x^2+8x+66x+44 Now we want to combine like terms to get:

12x^2+74x+44

Part B:

The degree is your highest exponent which in our case is 2

You would classify by how many different numbers you have:

This would be a trinomial because you have three different numbers: (12x^2, 74x, and 44)

Highest degree= 2

Classification= Trinomial

Part C:

Part A demonstrates the closure property because it shows that the polynomials are closed under the operations of adding, subtraction, and multiplying

Hope this helps ;)

it is x equals 3   plese mark me really need it

step-by-step explanation:

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.
