Answer:
r= -6
Step-by-step explanation:
<u>Assuming we are finding r,</u>
- | -2r-1| = 11
-( 2r + 1 ) = 11
-2r -1 = 11
-2r = 12
r= -6

Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)
