Answer: Between 14 and 18 years
Step-by-step explanation:
There are no dots in that area.
Answer:
A'(-1,-3)
B'(-2,-2)
C'(-4,-3)
Step-by-step explanation:
The rotation by 90° counterclockwise about the origin has the rule
So, the vertices of the triangle ABC have the images:
see attached diagram for details.
Fine the mesurments around and then fine the area
The perimeter of these can be found by adding length and width and then multiplying by two.
Rectangle A: (with all of the variables already doubled)
2x + 16 + 2x - 2
2x + 2x + 16 - 2
4x + 14
So rectangle A's perimeter is 4x + 14.
Rectangle B: (Still with all the variables already doubled)
8x + 10 + 6x - 4
8x + 6x + 10 - 4
14x + 6
So rectangle B's perimeter is 14x + 6
And now to subtract the two.
(7x + 3) - (4x + 14)
14x + 6 - 4x - 14
14x - 4x + 6 - 14
10x - 8
So it would be C.
