Answer:
9
Step-by-step explanation:
Area of a triangle=(base*height)/2
1) Input the values
54=(12h)/2
2) Multiply both sides by 2
54*2=(12h/2)2
108=12h
3) Divide both sides by 12
108/12=12h/12
9=h

Answer:
B) y = x + 2
Step-by-step explanation:
Coordinates of point C =
Coordinates of point D=
To find the equation of segment CD
Formula : 
Substitute the values in the formula :
y-12=x-6
y=x+6
When two lines are perpendicular to each other the product of their slopes is -1
Let the slope of perpendicular line be x
So, -1 \times x = -1
So, x =1
General equation : y = mx+c
So, Option B has slope = 1
So,the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8) is y = x + 2

I'd suggest you get rid of the fraction first. Mult. every term by 3. You will get
3y^2 + 10y + 3 = 0
From inspection, with coefficient a=3 and coeff. c = 3, the binomial factors could possibly begin with y or 3y: for example, y+1; also, the binom. factors may end in +1. Let's try the possible binomial factor 3y + 1.
Note that 10y separates into 9y+1y.
Then 3y^2 + 10y + 3 = 0 becomes
3y^2 + 9y + 1y + 3 = 0
Let's apply factoring by grouping:
3y^2 + 9y + 1y + 3 = 0
3y*(y + 3) + 1(y + 3) so y+3 is indeed a common factor.
Factoring y+3 out, we get (y+3)(3y + 1), which prove to be the correct set of factors. Multiply these together to ensure that the product is indeed y^2 + (10/3)y + 1.
