The answer is C. This is because if you multiply 7:5 by 3, you get 21:15.
I need the graphs to help you, sorry ;_;
Answer:
See proof below
Step-by-step explanation:
Two triangles are said to be congruent if one of the 4 following rules is valid
- The three sides are equal
- The three angles are equal
- Two angles are the same and a corresponding side is the same
- Two sides are equal and the angle between the two sides is equal
Let's consider the two triangles ΔABC and ΔAED.
ΔABC sides are AB, BC and AC
ΔAED sides are AD, AE and ED
We have AE = AC and EB = CD
So AE + EB = AC + CD
But AE + EB = AB and AC+CD = AD
We have
AB of ΔABC = AD of ΔAED
AC of ΔABC = AE of ΔAED
Thus two sides the these two triangles. In order to prove that the triangles are congruent by rule 4, we have to prove that the angle between the sides is also equal. We see that the common angle is ∡BAC = ∡EAC
So triangles ΔABC and ΔAED are congruent
That means all 3 sides of these triangles are equal as well as all the angles
Since BC is the third side of ΔABC and ED the third side of ΔAED, it follows that
BC = ED Proved
Answer:
The third equation where 2 liters of water evaporate from a pool every day is linear
Step-by-step explanation:
One way to think about this is that the other equations would require exponents, or solving non-algebraically would require know the subsequent output.
However, if 2 liters of water evaporate from a pool every day, the equation would be y= number of liters in pool - 2x
Answer:
I think it would be 208
Step-by-step explanation:
Well if the length is 76 and the total perimeter is 284, I would think that all you would have to do is subtract 284 by 76 to get 208. Sorry if this is confusing never been good at explaining things.
Hope this helps! Have a wonderful rest of your evening! :)
