Answer:![\frac{(w-3)(w-4)}{(w+5)(w-4)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%28w-3%29%28w-4%29%7D%7B%28w%2B5%29%28w-4%29%7D%20)
If we want to expand the brackets, the fraction would be:
Explanation:First, we can note that:
w² + w - 20 can be factorized as follows:
w² + w - 20 = (w+5)(w-4)
The given expression already has a (w+5) in the denominator, therefore, all we need to do is multiply the denominator by (w-4)
Since we want the new fraction to be equivalent to the original one, therefore, as we multiply the denominator by (w-4), we will also multiply the numerator by (w-4) to ensure that the value of the fraction is unchanged.
Based on the above, the new fraction would be:
![\frac{(w-3)(w-4)}{(w+5)(w-4)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%28w-3%29%28w-4%29%7D%7B%28w%2B5%29%28w-4%29%7D%20)
If we want to expand the brackets, the fraction would be:
![\frac{w^2 - 7w + 12}{w^2 + w - 20}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bw%5E2%20-%207w%20%2B%2012%7D%7Bw%5E2%20%2B%20w%20-%2020%7D%20)
Hope this helps :)
10 x 15=150
150 is the answer
Answer:
Step-by-step explanation:
For t in weeks, a reasonable exponential function describing the dept (d) might be ...
d = 10(1.03^t)
Then, after 8 weeks, the depth is predicted to be ...
d = 10(1.03^8) ≈ 12.67 ft ≈ 13 ft
Answer:
-4/2 is equal to -2.
-2 times -4 is equal to 8.
Therefore, (-4)-4/2
Answer:
1
