I believe the answer is C
A square, rectangle, rhombus (I think)
$38.95-$29.95= $9
$9= 900¢
900¢/3¢= 300
Ans: She used 300 minutes.
Answer:

Step-by-step explanation:
The formula for the area of a triangle is 
The triangles that can be made is the triangle that has legs 20 and 50 and the triangle that has legs 20 and 10.
Since there are 2 of each triangles, we get:

The answer that fits is the first option.
20x^2y - 4xy
First, we look at what terms are common between each term.
There is a 4 present in the last term, and 4 is a factor of 20, so that is one factor.
Each term also includes at least one x, and one y, so x and y are also factors.
We can factor a 4, an x, and a y out of this.
<h3><u>4xy(5x - 1) is the fully factored form of this binomial. </u></h3>
