The answer would be y=-4 and x=4, so pick which ever number/letter has this answer.
Answer; c^2 = a^2 + b^2
c = 17 inches
a = 8 inches
b^2 = c^2 – a^2
b^2 = 17^2 – 8^2
b^2 = 289 – 64
b^2 = 225
b = square root of 225
b = 15 inches ≈ c.
The simplification of 3log(x + 4) – 2log(x – 7) + 5log(x - 2) - log(x^2) is 
<u>Solution:</u>
Given, expression is 
We have to write in as single logarithm by simplifying it.
Now, take the given expression.

Rearranging the terms we get,







Hence, the simplified form 
First of all we will divide 8 by 2 to get the number of full practices in the morning, which is 4. Next divide 7 by 2 to get the number of practices in the afternoon. Although there is a remainder, that remainder is not a full practice session, so we only count the whole numbers which is 3.
4 + 3 = 7 full practice sessions.
