M={2,3,4,6,7} D={2,4,6} intersection of M and D. union of M and D​
SCORPION-xisa [38]

Answer:

M ∪ D= { 2, 3, 4 , 6 , 7}

M ∩  D= { 2, 4 , 6}

Step-by-step explanation:

UNION OF SETS : The union of two sets P and Q  is the set of elements which belong in A or in B or in both.

Here,  M =  {2,3,4,6,7}   D  =   {2,4,6}

⇒ M ∪ D= { 2, 3, 4 , 6 , 7}

INTERSECTION OF SETS :  The intersection  of two sets P and Q  is the set of elements which belong in A and B both.

Here,  M =  {2,3,4,6,7}   D  =   {2,4,6}

         ⇒ M ∩  D= { 2, 4 , 6}

Factor the polynomial.
mixer [17]

Answer:

Final answer is choice B. (5x-2y)^2

Step-by-step explanation:

We need to factor the given expression 25x^2-20xy+4y^2

25x^2-20xy+4y^2

=25x^2-10xy-10xy+4y^2

=5x(5x-2y)-2y(5x-2y)

=(5x-2y)(5x-2y)

=(5x-2y)^2

Hence final answer is choice B. (5x-2y)^2

What’s the domain and range for (2,4) (5,3) (-1,-4) (0,9) (-3,1)
Citrus2011 [14]

Step-by-step explanation: In this problem, we're asked to state the domain and range for the following relation.

First of all, a relation is just a set of ordered pairs like you see in this problem. The domain is the set of all x-coordinates for those ordered pairs. So in this case the domain or D is {2, 5, -1, 0, -3}.

The range is the set of all y-coordinates for those ordered pairs. So in this case our range or R is {4, 3, -4, 9, 1}.
