Answer:
14/42
Step-by-step explanation:
Use the keep change flip strategy or butterfly multiply
Given side 28 is equal to side 4
28÷4=7
therefore times all numbers on smaller shape by 4 to get sides of larger shape, add the numbers on larger shape together to equal 238
Perimeter of larger shape is 238
The question is to find to rule
9 +9 =18
18+9=27
27+9=36
36+9=45
249.8 so that would be 2 cents off not a lot though.
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>
