2 lines in a plane can have these positions:
i) they can be
parallel, if they share no common point.
ii) are
intersecting, if they have one common point.
ii) they are
coincident if they have 2 common points.
AB and EB share 1 common point, B, therefore they are
Coincident.
Answer:
3 and 5/12
Step-by-step explanation:
To find how much flour you need, subtract how much sugar you need from how much total you need of sugar and flower. To do this, turn both numbers into improper fractions. This means 3 and 2/3 turns into 11/3 as there are 3 thirds per whole, and there are three wholes plus the 2 thirds, equaling 11/3. The 1/4 is already an improper fraction, so you can move on.
Now you just covert them to have the same denominator by multiply 11/3 by 4 on top and bottom and 1/4 by 3 on both the top and bottom to get 44/12 and 3/12. Now you just subtract 44/12-3/12 and get 41/12. Made into a mixed number that is 3 and 5/12.
2*2*23 is the answer. Hope this helps.

Answer:
-7,1
Step-by-step explanation:
x^2+14x+49=0
x^2+14x/2=0-49
x^2+7x=-49
x^2+(7x)²=-49+49
x²+7x²=0
(x+7x)²=0
√(x+7x)²=0
x+7=0
x=-7,1
