an isosceles triangle has two sides of equal length a and a base b the perimeter of the triangle is 15.7 inches so the equation to solve is 2a + b =15.7 if we recall that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side which lengths make sense for possible values of b ?

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

step-by-step explanation:

infinity is the answer
