The correct answer is C...
Answer:
GD = 6 in.
Step-by-step explanation:
Because the lines are medians AG = 2GD.
So x + 5 = 2(x - 1)
x + 5 = 2x - 2
5 + 2 = 2x - x
7 = x.
Therefore GD = 7 - 1 = 6 (answer).
Everything is divisible by five, so pull out five
5(-k^2+4k-6)
Answer:
3(x + 1) + 6 = 33
3x+3+6=33
3x+9=33
3x=33-9
3x=24
x=24/3
x=8
Step-by-step explanation:
hope it help ^_^
Answer:
x = 7
Step-by-step explanation:
Remember that the axis of symmetry (a vertical line that passes through the vertex) is exactly halfway between the two x-intercepts. Thus, the x-coordinate of the vertex is 7.
