Answer :-
R= 7
Explanation:-
The diameter is 2 times the radius
So the radius is 14/2 =7
Answer:
-2r^3+4r^2+12r-4
Step-by-step explanation:
6r^3-2r^2+12r-4-8r^3+6r^2
(6r^3-8r^3)+(-2r^2+6r^2)+12r-4
simplify
-2r^3+4r^3+12r-4
Step-by-step explanation:
c
5 cupcakes = $7.5
18 cupcakes = $27
If we do it algebraically, we get
x + y = 420
This is the simplest equation. You see now this is a linear pair in two variables. Thus, there will be infinitely many solutions.
E.g - 419 + 1 = 420
42 * 10 = 420
21 * 20 = 420
etc,....
