Step-by-step explanation:
Let the third side of the triangle be 
.
We can apply the cosine rule to find 
.
We evaluate to obtain;
We take the positive square root of both sides to obtain;
The correct answer is B.
Answer:
5x + 12
Step-by-step explanation:
simplify f(x) and g(x)
g(x) = 4*2 -3*2 +5
g(x) = 8 -6 + 5
g(x) = 7
and
f(x) = 4*2 + 5x -3
f(x) = 8 + 5x - 3
f(x) = 5x + 5
So (f + g)(x) = f(x) + g(x)
(f + g)(x) = (5x + 5) + (7)
(f + g)(x) = 5x + 12

Answer: (x,y)---->(4x,4y)
Step-by-step explanation:
1. By definition, dilation is as a transformation in which the figure is enlarged or reduced.
2. For dilation you have:
- A scale factor, that determines how much the figure will be reduced or enlarged.
- The center of dilation, which is defined a a fixed point in the plane.
3. If the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply each coordinate of the original figure by 4, then. Then, the rule is:
(x,y)---->(4x,4y)
Answer is C. 0.6 (6 is repeating)
