Answer:
12 cm
Step-by-step explanation:
AB and DC are parallel to each other, so they are the same length. Set their lengths equal to each other and solve for x
4x = 7x - 9
4x - 7x = 7x - 7x -9
-3x = -9
-3x/-3 = -9/-3
x = 3
Now solve for AB.
AB = 4x
AB = 4(3)
AB = 12
Blank one and two are both 4.
A square rotated about it send her by 360° maps onto itself at D) 4 different angles of rotation. You can reflect a square onto itself across B) 4 different lines of reflection.
A square is a geometric figure which has all its four sides equal and all its interior angles are right angles(90°.)
Therefore, it can be rotated about its center by 360°
It maps onto itself at 4 different angles of rotation (at every 90° angle).
We can reflect a square onto itself across 4 different lines of (2 across the non-parallel sides and 2 across the vertices of the square.) reflection.

Answer:
448 kilometers
Step-by-step explanation:
So, since the car goes 112 kilometers in one hour, you need to multiply 112 by 4.
112*4=448
The police car drives 448 miles in 4 hours.
The interior angles of a shape are the angles inside the shape. The exterior angles are the angles formed between a side-length and an extension. Rule: Interior and exterior angles add up to 180 ° 180\degree 180°.
