Answer:
A. Yi did not list all the factors of 63
Step-by-step explanation:
Did the quiz
see explanation
The error is that the factors of 3 and 21 are missing from the list for 63
Factors of 42 : 1, 2, 3, 6, 7, 14, 21, 42
Factors of 63 : 1, 3, 7, 9, 21, 63
common factors are : 1, 3, 7, 21
greatest common factor = 21
it is SAS
because BC is common side in both triangles
so
now two triangles have 2 sides equal and 1 angle equal so
it is congruent by SAS rule
4 divided by 5 is equal to 0.8. This decimal can also be written as a fraction. 0.8 = eight tenths or 8/10 (4/5 in its reduced form).
y=(x-5)^2-4
this is because the -4 drops it below the line and then x-5^2 stays where it is so mainly the minus in the domian and range and the -4 moves it over
1 is the value of x
