Which triangles are right triangles? Check all that apply. A cube. The top face has points A, B, D, C. The bottom face has points E, F, H, G. Triangle A D G Triangle A F H Triangle B C H Triangle B E H Triangle B F G Triangle C D G Triangle E F G Triangle D F G

  AFH, BFG, CDG, EFG

Step-by-step explanation:

For this answer, we assume the edges of the cube are ...

  AB, AC, AE, BF, BH, CD, CG, DH, EF, EG, FH, GH

The right triangles will include at least one edge and any of the other 6 points. The right triangles are ...

  AFH, BFG, CDG, EFG . . . . . . . an edge is highlighted

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

a:
