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.
Answer:
80
Step-by-step explanation:
10- w = 90
w = 90 -10
w = 80
Make ratios.
12/16: 15/x
cross multiply
12(x) = 12x
16(15) = 240
12x = 240
isolate the x, divide 12 from both sides
12x/12 = 240/12
x = 20
D) 20 km is your answer
hope this helps
