Good evening
Answer:
[tex]-\frac{225}{17}[/tex]
Step-by-step explanation:
Note :_________________
in equality like this
[tex]\frac{a}{b} =\frac{c}{d}[/tex]
we can use what we call the product of means equal to the product of extremes
i e : a×d = b×c
______________________
then
[tex]\frac{-17}{15} =\frac{15}{n}[/tex]
equivalent to
-17n = 15×15
equivalent to
-17n = 225
equivalent to
[tex]n=-\frac{225}{17}[/tex]
HOPE This Helps.
