Answer:
41, x=-5
Step-by-step explanation:
m<DEY = m<FEY, by angle bisector theorem
(9x-4) = 41
9x = 45
x = 5
m<DEY = 41
3/4 of 3600..." of " means multiply
3/4 * 3600 =
10800/4 =
2700 <==
Answer:
3x+3
Step-by-step explanation:
add up x-3,x+6 and x
combine like terms
x+x+x-3+6=3x+3
The axis of symmety is the x value of the vertex
to find the x value of the vertex of ax^2+bx+c=0
x value=-b/2a
3x^2+bx+4=0
3/2=vertex
-b/2(3)=3/2
-b/6=3/2
times 6
-b=18/2
-b=9
times -1
b=-9
