If -1<x<0, which of the following expressions is the largest? A.-1 B.x C. 2x D.x^3

5 0

The answer is C-2x because you can substitute a number between -1 and 0 for x, so for example .5, and try out all the choices with .5. Ultimately you get 2(.5) as the largest number, so the answer is C.

In an isosceles triangle the length of the base is 10 cm

lawyer [7]

The computation shows the radius of the circle that is inscribed in the isosceles triangle will be 3.33cm.

<h3>How to calculate the radius?</h3>

From the information given, the isosceles triangle the length of a base is 10 cm and the length of a leg is 13 cm.

Let A = area of the triangle

Let S = semi perimeter of the triangle.

The radius will be: = A/S

where,

$S = \dfrac{(a + b + c)}{2} = \dfrac{(13 + 13 + 10)}{2} = 18$
