Answer: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
the height of a triangle is 2*(x-2)

Subtract 430 and 512 and turn into a percent
82%
Than 430+512is942
Divide by 82%is11.487804
Skip a few times until u reach 11.48
Add 4+8 and then dvd:1 dvd to buy
So 4+8is12 plus 11 is 23 and one dvd it’s 24
So the answe is 24%
If it is a triangle it would be 149
