It's because if you are only working with positives, then the first quadrant is the only one that can help you, if you draw the other 3, then you just take up too much space to represent something you don't even need to show
This equation uses two properties of logarithms:


So you could take the ln from left and right hand side in the equation, and get:
(2-x)ln 3 = x ln 5
then
2 ln 3 - x ln 3 - x ln 5 = 0 =>
x(ln 3 + ln 5) = 2 ln 3
so x = 2 ln 3 / (ln3 + ln5)
Now using the 1st property you can say 2 ln 3 is ln 3² = ln9
and using the 2nd property you can say ln3 + ln5 = ln15
so x= ln9 / ln15
Answer:
no
Step-by-step explanation:
By the Side-Angle-Side Similarity Theorem (SASS), if two sides of a triangle are in proportion with the corresponding sides of another triangle, and the included angles are congruent, then the triangles are similar.
(9 x 10^2)(2 x 10^10)
(9 x 100)(2 x 10,000,000,000)
(900)20,000,000,000) = 1.8e +13
