Let the number = x
12 + x = 3x - 32
x = 3x - 44 Subtract 12 from both sides
-2x = -44 Subtract 3x from both sides
x = 22 Divide by -2
False, it would not make a right triangle
A = 7x, c = 4x, s = 3x
a = s+52
7x = 3x+52
4x = 52
x = 13
c = 4x = 52
Caroline gets 52.
The draw an inscribed polygon inside the circle, the very thing to do is to draw the circle. Thus, the answer is the fourth choice, "Place a point on your paper and then use a compass to construct a circle". After which, we can locate the vertices of the polygon in the circumference of the circle and connect them to make the polygon.
