B. x+4=-12

1) how can we get equation B from equation A?

choose 1

(Choice A) rewrite one side (or both) using the distributive property

(Choice B) rewrite one side (or both) by combining like terms

(Choice C) multiply/divide only one side by a non zero constant

(Choice D) multiply/divide both sides by the same non zero constant

2) based on the previous answer ,are the equations equivalent? in other words ,do they have the same solution?

Step-by-step explanation:

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'.
