Answer:
C
Step-by-step explanation:
It's stated that EFI is dilated by a scale factor of 1/3.
Dilating gives the following
FH = 1/3×FE
FG = 1/3×FI
HG = 1/3×EI
Sense ΔEFI is reflected over a line FG/FH = (1/3×FI)/(1/3×FE) = FI/FE
Notice that the following shows triangle similarity, meaning ΔEFI ~ ΔHFG.
The only answer choice that shows this would be FE/3 = FH, FI/3 = FH, and
EI/3 =HG ΔEFI ~ ΔHFG.

Step-by-step explanation:
Answer:4025
Step-by-step explanation:
Answer:
zero, because the discriminant is negative
Step-by-step explanation:
By writing the quadratic formula, we have the discriminant written in the root as;
b^2-4ac
Now, given the expression, we can see that the discriminant here is -19
What this mean is that we have a negative discriminant
Hence, we can conclude that the roots are complex and as such, none of the roots are real
