Step-by-step explanation:
sorry
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: (g+5)-8
Step-by-step explanation:
480=60(v+s)
480=60v+60s
8=v+s
s=8-v...
480=80(v-s) using s from above we get:
480=80(v-(8-v))
6=v-8+v
6=2v-8
2v=14
v=7, and since s=8-v, s=1
So the rate of the team is 7m/s while the rate of the stream is 1m/s
