It’s a cus they are all half the value of each other
40n-15 can be broken down by
5(8n-3)
B.) 20
If x goes from 2 to 4 it was multiplied by 2. you would do the same to the y. 10*2=20
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.
2. Therefore, let's call
x: the smaller one.
y: the larger one.
3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:
x+y
4. So, the area of the room is:
(x+y)(x+y)
(x+y)</span>²
Therefore, the answer is: (x+y)²
Answer:
Original cost was $19.99
Step-by-step explanation:
100% - 15% = 85%
16.99 / 0.85 = 19.99
To check:
19.99 * 0.15 = 2.998
19.99 - 2.998 = 16.992 = 16.99
Correct!!
