The pair of given triangles which satisfied the HL theorem of congruency is given by option C. Both right triangles with hypotenuse and one corresponding leg congruent.
HL theorem also named as Hypothenuse Leg theorem,
It states hypotenuse and any one leg of one right angled triangle is congruent to hypotenuse and corresponding leg of another right angled triangle.
This implies both the triangles are congruent using HL theorem.
To check which pair of triangles are congruent using HL theorem are as follow,
a. In the first pair of right angled triangles only hypotenuse is marked as congruent side of two different triangles.
So it is not true.
b. In the second pair of triangles,
Both the triangles are obtuse angled triangle.
It does not satisfied HL theorem.
So , it is also not true.
c. In the third pair of the right angled triangle,
Hypotenuse of both the triangle are marked congruent.
One of the corresponding leg is also congruent.
It satisfied the HL theorem.
And both the triangles are congruent to each other using HL theorem.
Option C. is true.
d. IN fourth pair of triangles,
Triangles are not right angled triangle.
It satisfied the SSS (Side -Side- Side) congruency theorem.
It is not a correct option for HL theorem.
Therefore, pair of triangles which satisfied the HL theorem of congruency is option C. Both right triangles.

Answer:
Step-by-step explanation:
1) (xy+ 9y + 2) and (xy – 3)
Each term of second expression will be multiplied by first bracket.
xy(xy+9y+2) -3(xy+9y+2)
x²y²+9xy²+2xy-3xy-27y-6
x²y²+9xy²-xy-27y-6
2)(2xy + x + y) and (3xy2 – y)
3xy²(2xy+x+y) -y(2xy+x+y)
6x²y³+3x²y²+3xy³-2xy²-xy-y²
6x²y³ – 2xy² + 3x²y² – xy + 3xy³ – y²
3) (x – y) and (x + 3y)
x(x-y) +3y(x-y)
x²-xy+3xy-3y²
x²+2xy-3y²
4) (xy + 3x + 2) and (xy – 9)
xy(xy + 3x + 2) -9(xy + 3x + 2)
x²y²+3x²y+2xy-9xy-27x-18
x²y²+3x²y-7xy-27x-18
5) (x2 + 3xy – 2) and (xy + 3)
xy(x2 + 3xy – 2) +3(x2 + 3xy – 2)
x³y+3x²y²-2xy+3x²+9xy-6
x³y+3x²+3x²y²+7xy-6
6) (x + 3y) and (x – 3y)
x(x + 3y) -3y(x + 3y)
x²+3xy-3xy-9y²
x²-9y² ....
Answer: (xy + 9y + 2) and (xy – 3) —> x3y + 3x2 + 3x2y2 + 7xy – 6
(2xy + x + y) and (3xy2 – y) —> 6x2y3 – 2xy2 + 3x2y2 – xy + 3xy3 – y2
(x – y) and (x + 3y) —> (x + 3y) and (x – 3y)
(xy + 3x + 2) and (xy – 9) —> x2y2 + 3x2y – 7xy – 27x – 18

Answer:
Step-by-step explanation:
When we talk about a reasonable domain for a function, we refer to all values inside the domain set that makes sense to the problem which models the function. For example, if the function models people's age, then the reasonable domain must be all positive integers.
In this case, we have the function
Where represents the number of cars.
The mathematical domain refers to the comple domain set, using negative and positive numbers. However, the mathematical domain doesn't make sense to this problem, because the domain represents cars, and they cannot be represented by negative numbers and decimals.
So, the reasonable domain to this function is the set of all natural numbers, because they are positive and integers.
Therefore, the right answer is the first choice.
