<span>The identity element when applied does not change the other elements hence in multiplication 1x7=7 and 1x5=5 the elements 5 and 7 do not change for addition its 0 such as 0+10=10.
</span><span>Identity for multiplication is 1, for addition its 0</span>
Answer:
a) See below
b) 
c) 
Step-by-step explanation:
<u>Part A:</u>
We can draw 3 lines from A to D, B to E and F to C such that all of the lines pass from the center. This will form 6 equal (congruent) triangles.
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
<u>Part B:</u>
Area of each triangle = 1/2 (Base)(Height)
Where Base = 12 in. and Height = 10.4 in.
Area = 1/2 (12) (10.4)
Area = 6 (10.4)
Area of each triangle = 62.4 in.²
<u>Part C:</u>
Since the table is mage up of 6 equal triangles:
So,
Area of the table = 6 (Area of each triangle)
Area of the table = 6 (62.4)
Area of the table = 374.4 in.²

Answer:
3/26
Step-by-step explanation:
The face cards are: Jack, Queen, and King. There are only three face cards for each of the 4 suits.
Among the 4 suits, two of them are red: diamonds and hearts. And, each of these two has 3 faces. That means that in a deck of 52 cards, there are 2 * 3 = 6 cards that are both red cards and face cards.
Probability is (# times specific event can occur) / (# times any general event will occur).
Here, the specific event is drawing a card that is both red and a face card (of which there are 6 ways), and the general event is drawing a card (of which there are 52 ways):
P(draw a card that is both red and a face card) = 6/52 = 3/26
