Which triangle has hypotenuse Side B F? A cube. The top face has points G, B, C, F and the bottom face has points H, A, D, E. tr
jolli1 [7]

Answer:

ΔBFG

Step-by-step explanation:

Since top face points are

  • G, B, C and F

and bottom face points are

  • H, A, D and E

The side BF can be a hypotenuse of the triangle BFG only

This triangle is on the top face and all the rest given triangles are formed by the points that are not on the same face, therefore BF can't be a hypotenuse of those, as ether B or F is becoming a right angle of the triangles.

Let f(x) = 2x+4. If f(x) = 16, find x.
jeyben [28]

f(x)=2x+4

And we are given that f(x)=16 and want to find the value of x. Set f(x) to 16 and we get the equation:

2x+4=16

Subtract both sides by 4

2x=12

Divide both sides by 2

x=6

This is the answer. Let me know if you need any clarifications, thanks!
