Step-by-step explanation:

1 Simplify  425x\times 9311425x×9311  to  3957175x3957175x.

3957175x=420,6TD\times 103957175x=420,6TD×10

2 Simplify  6TD\times 106TD×10  to  60TD60TD.

3957175x=420,60TD3957175x=420,60TD

3 Break down the problem into these 2 equations.

3957175x=4203957175x=420

3957175x=60TD3957175x=60TD

4 Solve the 1st equation: 3957175x=4203957175x=420.

x=\frac{84}{791435}x=

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'.

what are the things "represented below"?

nobody can if you dont give the choices
