The correct answer for this very hard equation would happen to be 12 because 18+12 happens to equal 30 and 42-30 just so happens to equal 12
Answer:
not sure which is the origional-
if the big one is the origiinal, then 1/2
if the small one is the origional- then 2-1
Answer:
<h3>2√3</h3>
Step-by-step explanation:
The standard equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the center of the circle
r is the radius of the circle
Given the equation (x - 7)^2 + (y + 13)^2 = 12
On comparing;
r² = 12
Take the square root of both sides
√r² = √12
r = √12
r = √4*3
r = 2√3
Hence the radius of the circle is 2√3
Y=3x2+1
Hope this helped :)
Answer:
the answer is 
Step-by-step explanation:
You have to find the common denominator in order to get the sum.
multiply 5 to 
and you get
then to double check the sum, subtract it.
hope this make sense :/
