Answer:
a. 
b. No
Step-by-step explanation:
Given:
(3x-9) and 
=> the production of them is:
, we will use distributive law to solve this To do that. we first multiply by 3x then by -9. This is done as follows
= 
Then Open both brackets
= 
After that, we group the same terms
= 
=
(b) Is the product of (3x-9) and equal to the product of (9x-3) and
No, let find the product of (9x-3) and , we will use distributive law to solve this as the above example.
= (9x-3)
= 
=
= 
After that, we open the bracket to find the same terms
= 
= 
= 
As you can see ≠
Hope it will find you well.
P(7,6), Q(1,6), R(4,2)
We have PQ parallel to the x axis. We'll call that the base,
b = 7 - 1 = 6
The altitude is then the y difference h = 6 - 2 = 4
The area is 
Answer: 12 square units
In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:
(7,6), (1,6), (4,2)
(1,6), (4,2), (7,6)
The area is then half the absolute value of the sum of the cross products:
Answer:
110˚
Subtract 70 from both sides. Thus, a 70˚ angle and a 110˚ angle are supplements of one another
