Answer 1

A rectangle 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.

Part B: What are the degree and classification of the expression obtained in Part A?

Part C: How does Part A demonstrate the closure property for polynomials?

i got a and b i just need help with c
here is what i got for a and b

Part A: Area equals length times width
equals (4x + 5)(3x + 10) equals 12x^2 + 55x + 50

Part B: The degree is 2, It's a quadratic expression.

Answer 2

for part C, the closure property just means that multiplying two polynomials will also give you another polynomial as your answer

that should be sufficient

Answer 3

So i put Part C: It's means that multiplying two polynomials can give you another polynomial
