Answer:
Maybe it could be six or 30
Step-by-step explanation:
Log4(x(x-3))=Log4(-7x+21)
Log4(X the power of two -3x)=Log4(-7x21)
X the power of two -3x=-7x+21
x=3,x=-7.
Hypothenus is 9
one leg is 1/2 of 9=4.5
other leg 2=(9)2-(4.5)2
x2=81-20.25
x2=60.75
x=afersisht 8
You have 8 and 5/6 left
I’m pretty sure, but I don’t really know though
