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

2. Which of the following is the difference of two squares?
49m2 + 81n?
9a? -
- 466
99 36h
O 2x2 - 6y2
Answer:
[tex]9a^2-4b^2[/tex] is the correct answer.
Step-by-step explanation:
Difference of squares can be written as a^2 - b^2. This is equal to (a - b)(a + b)
In your answers, we see, 9a^2 - 4b^2. They are subtracting which is correct. 9 and 4 can also be rooted. 9 to 3 and 4 to 2 so
[tex]9a^2-4b^2[/tex] can be written as [tex](3a-2b)(3a+2b)[/tex]
The expression that is the difference between the two squares is 9a² - 4b⁶.
The correct option is B.
What is subtraction?Mathematical operations like subtraction exist. It is employed to delete words or objects from the phrase.
To find the difference between the two squares,
let a² and b² be the two terms.
So, a² - b² results in (a - b) (a + b).
From the given choices,
9a² - 4b⁶ = (3a)² - (2b³)²
As per the formula the expression can be rewritten as,
(3a - 2b³) (3a + 2b³)
Therefore, the required expression is 9a² - 4b⁶.

A number consists of two digits. The digit at the ten's place is
two times the digit at the unit's place. The number formed by
reversing the digit is 27 less than the original number. Find
the original number?
[CMAT 2011]
9514 1404 393
Answer:
63
Step-by-step explanation:
Reversing the digits changes the value by a factor of 9 times the difference in the digit values. Here, this means the digits differ by 27/9 = 3. If one digit is double the other, the higher digit is 2×3 = 6.
The number is 63.
_____
If you like, you can work through the algebra of it. Let the original number have tens digit x and ones digit y.
original number value = 10x +y
reversed number value = 10y +x
difference of values = 27 = (10x +y) -(10y +x) = 9(x -y)
The tens digit is twice the ones digit, so we have ...
x = 2y
Substituting in the difference equation, we have ...
27 = 9(x -y)
3 = (2y -y) = y . . . . . divide by 9, substitute for x
x = 2(3) = 6
The number is 10x+y = 63.
