Answer:
20√5 - 10√10
Step-by-step explanation:
6√20 + 8√5 - 5√45
first, 6√20 and 5√45 need to be simplified. 8√5 cannot be simplified any further:
6√20 = 6√4•5 = 6√2•2•5 = 6•2√5 = 12√5
5√45 = 5√8•5 = 5√2•2•2•5 = 5•2√2•5 = 10√10
now:
12√5 + 8√5 - 10√10
then, add the coefficients of 12√5 and 8√5
20√5 - 10√10
the left over numbers cannot be combined because they do not have a common radical, making 20√5 - 10√10 the final answer

what information is necessary to prove the triangles congruent by SSS, and what information is necessary to prove the triangles congruent by HL? show work pls
Answer:
SSS: LM = AB and MN = AC
HL: AC = MN
Step-by-step explanation:
✔️Information that is necessary to prove that both triangles are congruent by SSS are:
LM = AB
MN = AC
This will is because all three corresponding sides must be congruent to each other to satisfy the SSS Congruence criterion.
✔️Information necessary to prove that the triangles are congruent by HL:
We already know that one of the corresponding legs are congruent to each either. The additional information necessary to satisfy the HL Congruence criterion is to know the hypotenuse length of each which must be congruent to each other. This, information necessary would be:
AC = MN

Determine if a triangle can have the given side lengths. If yes, which type of triangle is formed by the side lengths. Choose the correct answer for both rows of the table. HELP GODDD PLZ PLZ PLZ HELP
Answer:
B and H.
Step-by-step explanation:
By the triangle inequality, any two sides of a triangle must be greater than the remaining side.
Triangle 1)
The side lengths are 9, 40, and 41.
We only need to check the two smaller sides. 9 + 40 = 49 which is indeed greater than 41. Therefore, this is indeed a triangle.
Remember that if:
[tex]c^2=a^2+b^2[/tex]
We have a right triangle.
[tex]c^2>a^2+b^2[/tex]
We have an obtuse triangle.
And if:
[tex]c^2<a^2+b^2[/tex]
We have an acute triangle.
In all of these, c is the longest side.
Therefore, we will substitute 41 for c and 9 and 40 for the others:
[tex]41^2\text{ }?\text{ }40^2+9^2[/tex]
Evaluate:
[tex]1681=1681[/tex]
Since the two values are equivalent, the first triangle is a right triangle.
Triangle 2)
Again, adding up the two smaller sides gives that 8 + 10 = 18.
However, 18 is less than 21, so it does not satisfy the triangle inequality.
Therefore, the given side lengths cannot form a triangle.
