Answer:
9
Step-by-step explanation:
you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.
So we would need to realize that the constant would be equal to (-6/2)^2 =(-3)^2 = 9
We have completed the square.
f(x) = 4*( x - 3)^2 + 20 is now in Vertex Form
Answer:
units
Step-by-step explanation:
The median is the line segment connecting the vertex with the midpoint of the opposite side.
<u>The midpoint has coordinates:</u>
- x = (-3 + 5)/2 = 2/2 = 1
- y = (3 + 1)/2 = 4/2 = 2
<u>Use the distance formula to find the distance between points (2, 7) and (1, 2):</u>

Angle (8x)⁰ and angle (2x+60)⁰ are congruent angles as corresponding angles.
So,
8x = 2x+60
8x - 2x =60
6x = 60
x=10
