Answer:
C
Step-by-step explanation:
So we need to understand what is rational numbers?
Rational number which can be written under this form: 
when x any are both integers and y
The question here is : Which property would be useful in proving that the product of two rational numbers. In math, when we talk about the product of at least two number, it implies to the multiplication in the operation.
Here, only answer C: 
with the condition 
and a, b, c and d are integers. Product of two integers is always an integer..
Answer:
9. x=102
10. x=56
11. x=104
12. x=138
Step-by-step explanation:
9. In this problem, they are alternate exterior angles, meaning they are the same value. x=102
10. x is a corresponding angle, meaning they are the same. x=56
11. There are consecutive interior angles. The sum of these two angles is 180. to find x, subtract 76 from 180. 180-76 = 104 x = 104
12. These two angles are verticle angles, meaning they are equivalent. x = 138
Answer:
Concept: Algebraic Analysis
- Those two symbols indicate one solution
- Those symbols indicate a range of values
- Indicates two bounded answers
- In an inequality there is always a solution
Answer: <u>11.</u>
Step-by-step explanation: All you'd have to do in order to achieve this answer is by dividing 410 by 40 which gives you the answer of 10.25. In order to fit everyone they'll need a rounded number of buses; equalling 11.
To find the area, use A= bh (base x height), or A = lw (length x width)
There are 3 feet in 1 yard
3 x 5 = 15
4 x 3 = 12
15 x 12 = 180
The flower bed is 180 ft²
hope this helps
