Answer:
1.Many pairs of triangles designed into a building, for example as roof ends, would be congruent, so the roof beam and the top edges of the walls are horizontal.
2.The congruent triangle is used in most of the building that are design to stay in bad conditions and Strong winds for Example the Sydney Bridge.
3.in real life two triangles are rarely exactly congruent. However they are crucial in the construction of large man-made structures. This is because a triangle is the most stable shape and the congruence is needed to create even surfaces.
<span>f(x)=(<span><span>3x−1)/</span>2<----Starter </span></span>
y = (3x-1)/2
switch x and y
x = (3y-1)/2
2x = 3y-1
2x+1 =3y
y = 2/3*x + 1/3
f^(-1) (x) = 2/3*x + 1/3
f^(-1) (4) = 2/3*4 + 1/3 = 8/3 + 1/3 = 9/3 = 3
I hope this helps. ;)
That fraction is fully simplified. :)
Answer:
104
Step-by-step explanation:
This is not a distributive property question though.
A distributive property has a number (a) outside the parenthesis
a(b+c)
so in this case a(40+64)
then you would multiply a by both numbers
40a+64a
then add them together
104a
However if it is a number outside the parenthesis and not a variable, it will come out different
For example
5(40+64)
(5*40)+(5*64)
200+320
520
Hope this helps!
