Step-by-step explanation:
for the relationship of lengths of internal chords the product of both segments of a chord is equal for all intersecting chords.
in our case
(x+8)×8 = 7×16 = 112
8x + 64 = 112
8x = 48
x = 6
so, D-F = x + 8 = 6 + 8 = 14
so, C is correct
1. find equation
general solutions are:

for P(0,-11)

⇒

for p(1,-13)

and

solve for a and b:

the total equation is now:

To find the x-intercept set y=0 and solve for x
Answer:
C
Step-by-step explanation:
No, she didn’t use the entire fraction as the base, so wrote the expanded form wrongly.
and I know this cuz I took the test
The answer is A. It is not B because 9 is the product of 3 x 3. It can't be C because 1 is only the product of 1 x 1.
