Answer:
f(x) = 10
Step-by-step explanation:
for direct variation
f(x) = kx
substitute in for f(x) and x
40 = k*8
solve for k
40/8 = k*8/8
5 =k
now we have
f(x) = 5*x
let x=2
f(x) = 5*2
f(x) = 10

Answer:
Perimeter of each triangles are equivalent to 15.4 inches.
Step-by-step explanation:
Given:
A rectangle :
Length of the rectangle = 5 inches
Width of the rectangle =4 inches
As Bridget cuts it from one corner to the other corner,its forms two right angled triangle.
The diagonal will be treated as the hypotenuse.
Lets say that the length of the hypotenuse is 'x'.
Using Pythagoras formula:
⇒ 
Plugging the values:
⇒ 
⇒
⇒
⇒
inches
Now we have to find the perimeter :
Perimeter = Summation of length of all sides.
So,
Perimeter of each triangle = (length + width + hypotenuse)
⇒
⇒
inches
Perimeter of each triangle, as they are equally sized are same that is 15.4 inches.
Answer:
160
Step-by-step explanation:
one of the triangle faces:
4 × 6 = 24cm^2
theres 4 triangle faces so 24 × 4 = 96 cm^2
then u have to add on the square face which is 8×8 =64cm^2
total:
64 + 96 = 160cm^2
