nickles are 5cent (.o5 of $1) dimes are .1 of a dollar. this shows the addition in dollars of both values. </span>
<span>D) right
The slope between </span>(3,-2) (7,3) and <span>(3,-2) (-7,6) are opposite reciprocals of 5/4 and -4/5. If the slopes are opposite reciprocals they are perpendicular and have an angle equal to 90 degrees which makes it a right triangle. none of the distances are equal so it cannot be an isosceles right triangle.</span>
You didn't include the actual number in inches.
