False, it would not make a right triangle
Answer:
5
Step-by-step explanation:
The side with 4 cubes has a length of 2, the side with 2 cubes has a length of 1, and the side with 5 cubes has a length of 2.5.
2 x 1 x 2.5 = 5
I think it’s d for the standard equation
the equation 2x-4-1+x would be the answer
Because 2x+x = 3x and -4-1 = 5, the result would be 3x-5
