Answer:
x=0, -5/3
Step-by-step explanation:
Sin α = 12/13 opposite/hypothenue
cos α = 5/13 adjacent/hypothenue
tan α = 12/5 opposite/adjacent
Step-by-step explanation:
Remove the parentheses: 15a²-6ab+8a²+20+5ab-31+a²-ab Combine like terms: 24a²-2ab-11
Answer: 24a²-2ab-11
Answer:
Time = T half–years , Rate = 5 % per half year

Answer:
n=−5
Step-by-step explanation:
n−4−3n=3n+6−3n
−2n−4=6
Step 2: Add 4 to both sides.
−2n−4+4=6+4
−2n=10
Step 3: Divide both sides by -2.
−2n
/−2
= 10
/−2
n=−5
