Answer:
Step-by-step explanation:
Distribute the x and you get f(x) - g(x)
(-x2 + 6x - 1 ) - (3x2 - 4x - 1)
-x2 + 6x - 1 - 3x2 + 4x + 1
-4x2 + 10x
Circumference = 2 · π · r or π · d
Radius = 7.8
7.8 × 2 = 15.6
15.6 × 3.14(π) = 48.984
Circumference = 48.984 rounded = 49
Area = π · r²
Radius = 7.8
7.8 × 7.8 = 60.84
60.84 × 3.14(π) = 191.0376
Area = 191.0376 rounded = 191
Hope this helped☺☺
Answer:
A is also 27.
B is 16 also.
Step-by-step explanation:
These are acute triangles they all almost have the same length except for the one different on the side. They would be isosceles if not for that.

Step-by-step explanation:
Each image point is twice as far from the origin as its preimage point. Each image segment is twice as long as its preimage segment. (LM=2, L'M'=4, for example)
The scale factor is 2.
