Answer:
Intersecting, but not perpendicular lines
When you graph it, it isn't gonna be apart, its gonna be intersecting
14 yards
Step-by-step explanation:
the area of a triangle is 0.5×b×h
so
plug in what you have
0.5×b×3=21
(3x0.5)b=21
1.5b=21
b=21/1.5
b=14
x= 3
AC = 22
hope it helps you...
Therefore (x,y)=(3,7)
put the second equation into the first
x+4=3x-2
x-3x=-2-4
-2x=-6
x=3
plug x=3 into the second equation
y=3+4=7
