Answer:x=7
Step-by-step explanation:
Here AD=6
AB=6 (tangents drawn from external point to a circle are equal)
Then BC=13-6=7
Now, CE=BC=7(tangents drawn from external point to a circle are equal)
EF=14-7=7
EF=FG=x=7(tangents drawn from external point to a circle are equal)
Answer:
B is incorrect because you could set them equal to each other
Answer:
Step-by-step explanation:
f(x) = x² is an up-opening parabola with vertex (0,0). There is one x-intercept, and that is the vertex.
g(x) = x²-7 is the equivalent to f(x) shifted down 7 units. Since the vertex is below the x-axis and the parabola opens upwards, it intercepts the x-axis at two points.
The answer for this question will be 20 ft
8= 4x2 so 5x4=20ft
