Which expression is equivalent to 3(m − 3) + 4? 3m + 1 3m − 5 3m + 13 3m − 3
2 answers:
So let's simplify this problem using the distributive property.
The first thing we want to do is change the minus to plus a negative. Now we can distribute or multiply this 3 times each of the terms inside the set of parentheses.
So we get 3 (m) + 3 (-3) + 4 and this simplifies to 3m + -5.
3m + -5 means the same exact thing as 3m - 5.

Answer:
Center = (5,-3) and radius = 7
Step-by-step explanation:
(5) If Oskar bisects the diameter of a circle, what is he trying to construct the radius of the circle.
(6) The given equation is :
The general equation of circle is given by :
...(1)
Where
(a,b) are the coordinates of the centre and r is the radius.
The given equation can be written as :
..(2)
Comparing equation (1) and (2) we get :
a = 5, b = -3 and r = 7
So,
Center = (5,-3) and radius = 7
Hence, this is the required solution.
