As part of a geometry assignment ellen drew an isosceles triangle. which of the following dimensions could represent the side lengths of the triangle ellen drew?

Hi, since there are no choices, I would just help you by giving the properties of an isosceles triangle. An isosceles triangle has 2 equal or congruent sides. Thus, two of its dimensions must be equal. For example, a triangle with sides 2 in, 2 in and 3 in, respectively, is an isosceles triangle.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
