Rhombus is a quadrilateral that has 4 congruent sides and diagonals bisect angles and diagonals which are perpendicular. Squares, rectangles and parallelograms do not have diagonals that are perpendicular. Answer thus is C. rhombus
The answer is 18, six sides and each side is 3 feet so:
6 x 3 = 18
The answer would be C. Hope this helped!
The perpendicular line to "Y = -4x + 10" that goes the the point (4,-6) is Y = 1/4x + 5.
The slopes are usually a fraction and a whole number. If the first slope is a whole number, it changes to a fraction, and vice versa. Also, if the first slope is negative, the perpendicular slope is positive and vice versa.
The y intercepts in this case are 10 (first slope) and 5 (dividing by 2) since it has to go through (4,-6). See graph below.
I hope this helps!
