Which of the following statements best describes operations with algebraic fractions? select all that apply. algebraic fractions contain variables, exponents, and operations with polynomials. to add and subtract with fractions, the denominators do not need to be the same. finding the least common denominator involves factoring. to add and subtract with fractions, the denominators must be the same.

the answer is

Finding the least common denominator involves factoring.
To add and subtract with fractions, the denominators must be the same.

Here two statements seems correct-

1. Algebraic fractions are fractions that contain variables, exponents, and operations with polynomials.

2. To add and subtract with fractions, the denominators must be the same.

To add or subtract algebraic fractions, first we find the lowest common multiple of the denominators.  Then we express all the fractions in terms of the LCD. And then we simplify the numerators.

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'.

answer: 0.1,0.85
