Answer:
x = 7
Step-by-step explanation:
First, solve by dividing y with x
When x = 6, y = 36
36/6= 6
6(x) = y is your equation.
Now plug in 42 for y
6(x) = 42
Isolate the x. Divide 6 from both sides
(6x)/6 = (42)/6
x = 42/6
x = 7
7 is your answer for x.

Answer:
Hi there!
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem.
Apothem: a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
Let the longest side of the triangle be x, then the length of one of the other sides of the triangle is 0.5x and the length of the third side is x - 10.
Then, x + 0.5x + x - 10 = 70
2.5x = 80
x = 80 / 2.5 = 32
Therefore, the length of the sides of the triangle are: 32, 0.5(32) = 16 and 32 - 10 = 22.
i.e. 32, 16, 22
