Answer:
(x+1)(x+9)
Step-by-step explanation:
using ac method
so there are 2 x so each go in a ( ) then you have to do the box method and get 9 at the right corner at the end. then get your 2 like terms combined then boom you got your answer.
Answer:
x = 3 or x = 8
Step-by-step explanation:
s(11-s)=24
11(s) -s(s) = 24
11s -s² = 24
s² - 11s + 24 = 0 ----> Solve using your favorite method.
By factorization,
s² - 11s + 24 = 0
(x-3)(x-8) = 0
hence x = 3 or x = 8

Answer:
CN = 7
Step-by-step explanation:
In the attached figure, we have drawn line CD parallel to AB with D a point on line MK. We know ΔMNT ~ ΔDCT by AA similarity, and because of the given angle congruence, both are isosceles with CD = CT. Likewise, we know ΔCDK is congruent to ΔBMK by AAS congruence, since BK = CK (given).
Then CD = BM (CPCTC). Drawing line NE creates isosceles ΔNEC ~ ΔTDC and makes CE = AB. Because ΔNEC is isosceles, CN = CE = AB = 7.
The length of segment CN is 7.
_____
If you assume CN is constant, regardless of the location of point N (which it is), then you can locate point N at B. That also collocates points T and K and makes ΔBMK both isosceles and similar to ΔBAC. Then CN=AB=7.
Either
y=mx+b
or
y=-1/m*x+k
