20 - 5 is her score after losing points:
15
Now, 15 + 10 is her score after her extra points.
25 points
Hope this helps!
8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
Answer:
AP is 11.25 so the answer is F
Step-by-step explanation:
Since they are similar triangles (due to the ~ symbol)
You can write this:
AC/XZ = AP/XQ
since XZ=12
XQ=5
AC=27
you can write:
27/12=AP/5
then cross multiply:
27x5=135
135/12=11.25
AP is 11.25
Factor the following:
x^2 - 4 x + 3
The factors of 3 that sum to -4 are -1 and -3. So, x^2 - 4 x + 3 = (x - 1) (x - 3):
Answer: (x - 1) (x - 3)
