Answer:
x=5
Step-by-step explanation:
Answer:
x+y=15
Step-by-step explanation:
Given equation of 
Differentiating both side 

It passes through the point (12,3) so

So equation of tangent passing through (12,3) is
as 
So x+y =15 will be the equation of tangent which passes though the point (12,3)
Answer:
There is no variable so -3 therefore cannot be a solution to this.
Answer:
Let a be the width and b the length
a+3=b
a*b=54
a(a+3)=54
a^2+3a-54=0
a=6
Ohio = 45,000, Cali = 160000, Texas = 270000, Connecticut = 5500, SC = 32000,
A would be true
B would be false
C would be false
D would be true, assuming "about" means you can round up a little.
hope this helped
