Binary Operations

The union of two sets A and B is denoted A ∪ B and

is defined as A ∪ B = {x|x ∈ A or x ∈ B}.

The intersection of two sets A and B is denoted A∩B

and is defined as A ∩ B = {x|x ∈ A and x ∈ B}.

Two sets are disjoint if they have no elements in common,

that is, A and B are disjoint if A ∩ B = ∅.

Amil took $65.00 to go shopping, and he bought 2 pair of jeans for $27.00 each. How much change will he have? Choose the express
k0ka [10]

Answer:

B) 65 – (2 x 27)

Step-by-step explanation:

65 is you total, 2 is the amount of jeans and 27 is the individual price of the jeans.

Since you want to know how much is <u>left over</u>, you subtract how much you spent which would be, in this case, the jeans.

You bought 2 jeans, each for 27 dollars so you multiply the two to see how much for both jeans.

Subtract that from the total.

Hope this helps! (^-^)

Since y already equals something, x + 1.75, we can put its equivalent x + 1.75 in its place in the other equation. 
See the image for the rest of the solution steps.

Square and Rhombus are the following quadrilaterals have diagonals that are always  perpendicular to each other.

C. Square

D. Rhombus

<u>Step-by-step explanation:</u>

This implies the diagonals of a square and rhombus are perpendicular. The diagonals of a square and rhombus are a similar length. In elementary geometry, the property of being opposite is the connection between two lines which meet at a right angle. The property stretches out to other related geometric items.  

Principally Perpendicular lines will be lines that cross at a right (90 degrees) edge. so when it goes under shape rhombus and square have the equivalent of a considerable number of sides parallelly.
