What is the area of the shaded region?
-BARSIC- [3]

Answer:

25π - 24 cm²

Step-by-step explanation:

area of circle:

A = πr²

A = π(5²)

A = 25π

Area of triangle:

base = 6

height = 5 - 1 = 4

(1/2)(6 * 4) = 12

there are 2 triangles so unshaded area is 24 cm²

Area of shaded region = 25π - 24 cm²

Is the sum of two monomials always a monomial? Is their product always a monomial?
Ivan

Sum of two monomials is not necessarily always a monomial.

For example:

Suppose we have two monomials as 2x and 5x.

Adding 2x+5x , we get 7x.

So if two monomials are both like terms then their sum will be a monomial.

Suppose we have two monomials as 3y and 4x

Now these are both monomials but unlike, so we cannot add them together and sum would be 3y + 4x , which is a binomial.

So if we have like terms then the sum is monomial but if we have unlike terms sum is binomial.

Product of monomials:

suppose we have 2x and 5y,

Product : 2x*5y = 10xy ( which is a monomial)

So yes product of two monomials is always a monomial.
