which of the following is equivalent to the expression below? log3 - log15 A) log(-12) B) log12 C) log(1/5) D) log5 thanks for the help : )

Step-by-step explanation:

First and foremost, we need to point out that if there is no base written on those logs, it is understood to be a base of 10. The next thing applies to the rules of logs in regards to the subtraction of them. Usually, subtraction and addition "undo" each other. But in logs, subtraction and division undo each other in a sense. The rule is:

Following that pattern, our solution, or simplification, of

log(3) - log(15) is

which, simplified and omitting the base of 10, is:

, choice C.

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'.
