Answer:
C. the quadrilateral is a square. The parallelogram is both a rhombus and a rectangle.
Step-by-step explanation:
All parallelograms are quadrilaterals. All rhombuses and rectangles are parallelograms, all squares are both rhombuses and rectangles.
A parallelogram is a rhombus when the diagonals bisect opposite angles.
A parallelogram is a rectangle if the diagonals are congruent to each other.
Since the given parallelogram has the properties of both a rhombus and a rectangle, it is a square. The correct answer is C.
I really hope this helps =)
Answer:
34
Step-by-step explanation:
(10)(4)−(4)(3)−2x−6x+8+(−3)(4)+(6)(3)−(2)(2)+8x−4
= 40+−12+−2x+−6x+8+−12+18+−4+8x+−4
Combine like terms:
= 40+−12+−2x+−6x+8+−12+18+−4+8x+−4
= (−2x+−6x+8x)+(40+−12+8+−12+18+−4+−4)
= 34
2 goes into 18 nine times.
3 goes into 27 nine times.
I didn’t see an image or anything but I looked it up and it said regular polygons, since they have the sides all the same length they must always be in the same proportions, and their interior angles are always the same.
