Answer:
2 days
Step-by-step explanation:
72d+300(.10)=210
-9+8k=7+4k
subtract 4k from both sides
-9+4k=7
add 9 to both sides
4k=16
divide both sides by 4
k=4
Answer:
36x
Step-by-step explanation:
You do 12 x 3 which equals 36. Then you add the x at the end.
A because it passes the vertical line test
X=4, x=-4
(x^2 - 16) can be factored.
(x-4)(x+4)
x-4=0
x=4
x+4=0
x=-4
