Answer:
1)12 2)
Step-by-step explanation:
Problem 1:
a(5)=25 a(3)=13
a(5)-a(3)=25-13=12

So, x + y = 42 and y - x = 5;
Then, y = x + 5;
Finally, x + x + 5 = 42;
2x + 5 = 42;
2x = 37;
x = 18.5;
y = 18.5 + 5;
y = 23.5;
An equilateral triangle have 3 congruent sides.
Divide the total (15x +3) by 3
(15x + 3)/3 = 5x + 1
Each side's length is 5x + 1
hope this helps
Step-by-step explanation:
The volume of a cone can be derived by writing an expression that represents the volume of one cone within the cylinder.
the expression for the volume of a cylinder is

the volume of a cone is a part of the volume of a cylinder

Hence the volume of a cone can be derived by dividing the volume of a cylinder by 3
