A rectangular piece of cardboard is four times as long as it is wide. You make a box by cutting squares with side length effects from the corners of the cardboard and turning up the resulting flops. Write an expression involving X and the original width of the cardboard W that represents the perimeter of the base of the box. Then simplify the expression. Explain what the possible values of X can be.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
