Answer:
many different triangles.
Step-by-step explanation:
The given information is the length of two sides of a triangle, these lengths are:
8ft and 11ft
So the third side can have different lengths (notice that we do not have any restriction in the angles neither)
Then the third side has a lot of different possible lengths, this means that we can make many different triangles with this information.
Remember that one of the criteria for congruent triangles is SSS, (side side side)
So if we know 3 sides, there is only one triangle that can be made with these sides, but if we only know two sides this is not the case.
Step-by-step explanation:
First,
(A intersect B) = {1,2,4,5} intersect {1,3,5,7}
= {1,5}
Now,
A'n B = (A) - (A intersect B)
= {1,2,4,5} - {1,5}
= {2,4}
Answer:
2w^2 -7w-2
Step-by-step explanation:
(4w^2 – 4w – 8) – (2w^2 + 3w – 6)
Distribute the minus sign
(4w^2 – 4w – 8) – 2w^2 - 3w + 6
I like to line them up vertically
4w^2 – 4w – 8
– 2w^2 - 3w + 6
-----------------------------
2w^2 -7w-2
8x-24
