Answer:
the first one is -(25/2) OR -12.5
THE Second one is -(125/8) or -15.625
Given CD is an altitude such that AD=BC , AB=3 cm and CD= √2 cm.
Let AD=x, Since given AB=3
AD+DB=3
x+DB = 3
DB = 3-x
Since ΔBCD is rght angle triangle, let's apply Pythagoras theorem



Since given AD=BC,let us plugin BC=x in above step.


6x=11
x=
Now we know AD=x=
and given CD=√2.
Let us apply Pythagoras theorem for ΔACD



= 2.315cm
She’ll have to make 4 more stitches in order to get 6 good ones. Each time she creates 3 she undoes 2 which after 4 more times would leave her with 6 good stitches.
Answer:
-5(y - 3)(y - 7)
Step-by-step explanation:
Factor -5 out of all 3 terms:
-5(y^2 - 10y + 21)
Continue the factoring:
-5(y - 3)(y - 7)
