BC = 6, EF = 12 Based on the given information, choose the similarity statement that you would use to say ABC~DEF. If you could
vovangra [49]

Answer:

The answer is "NOT"

Step-by-step explanation:

  • To demonstrate a similar statement we want to have yet another side or some other angle, however, the third section is not proportional.  
  • Its sides were equivalent in proportions (yeah sure they are) + corner by the by is not given.
  • There is no triangle angle provided so, that we can not enforce the SAS argument.  
  • It is not evidence of similarity between ABC ≈DEF.

How to solve a one step equation of R+3= -6 1/2 <br> please show all the work
IgorC [24]
Solve for R:
R + 3 = -(1/2 + 6)
Put 1/2 + 6 over the common denominator 2. 1/2 + 6 = (2×6)/2 + 1/2:
R + 3 = -(2×6)/2 + 1/2
2×6 = 12:
R + 3 = -(12/2 + 1/2)
12/2 + 1/2 = (12 + 1)/2:
R + 3 = -(12 + 1)/2
12 + 1 = 13:
R + 3 = -13/2
Subtract 3 from both sides:
R + (3 - 3) = -13/2 - 3
3 - 3 = 0:
R = -13/2 - 3
Put -13/2 - 3 over the common denominator 2. -13/2 - 3 = (-13)/2 + (2 (-3))/2:
R = (-13)/2 - (3×2)/2
2 (-3) = -6:
R = (-6)/2 - 13/2
(-13)/2 - 6/2 = (-13 - 6)/2:
R = (-13 - 6)/2
-13 - 6 = -19:
Answer:  R = (-19)/2
