Answer:
m=16/39
Step-by-step explanation:
-5(4m-2)=-2/3+6m
-20m+10=-2/3+6m
-20m-6m=-2/3-10
-26m=-2/3-30/3
-26m=-32/3
26m=32/3
m=(32/3)/26
m=(32/3)(1/26)
m=32/78
m=16/39
Your answer is going to be the first one: 3^2
We know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
<span>the height of a triangle is 2*(x-2)</span>
