What is the difference between a subset and a proper subset?
muminat

Answer:

A subset is when all of the elements in the subset are in the actual set. A proper subset is a subset which the actual set has at least on more element than the proper subset.

Step-by-step explanation:

For example, Set A, {1,2,3} is a subset of B {1,2,3}. But Set C, {1,2} is a proper subset of B. Set {5,8} is a subset of {2,5,8}.

What is the width of Averi's area model? (See picture)
shepuryov [24]

Answer:

Width = x² + 5x - 4

Step-by-step explanation:

By the definition of an area model,

Area = Width × greatest common factor

Since, Area = 4x² + 20x - 16

And greatest common factor = 4

4x² + 20x - 16 = 4(Width)

By dividing both the sides of the equation by 4,

\frac{4x^2+20x-16}{4}=\frac{4(\text{Width})}{4}

x² + 5x - 4 = Width

Therefore, width = (x² + 5x - 4) will be he answer.
