Let w = the walking time
the total time is given as 1 hr, therefore (1-w) = running time
Walking dist and running dist is the same
Write a distance equation: dist = speed * time
3w = 9 (1-w)
3w = 9 - 9w
3w + 9w = 9
12w = 9
w = 9/12 = 3/4 hrs walking back
Answer:
6x +2x squared - 4
that's the answer. you need to group the like terms
Yes I am
:)))))))))))))))))))))

Therefore the answer is 41
<u>Examining the question:</u>
We are given the expression:

We know from Basic trigonometry that:


<u>Simplifying the expression:</u>
Replacing these values in the given expression, we get:

Since the denominator of both the values in the denominator is the same:

We know that
=
, using the same property:

and we are done!
