Answer:
Step-by-step explanation:
Combine the opposite terms in r − 3 − r
.
3 | x+12 |=6
Start by distributing 3 to both x and 12
You get 3x+36=6
Subtract 36 from both sides
You then get 3x=-30
Divide 3 from both sides getting
x= -10
(A ∩ B) means "A intersection B". Your problem statement tells you the intersection contains
{3, 4}
Log 100 equals 2. If you use a scientific calculator it equals 2.
