x > -1
-2x+5 < 7
-2x<2
Now since you divide by (-1) to get positive 2,you need to flip the sign
(-2)/(-1)= 2 2/(-1)=-2
SO
2x>-2
x > -1
To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)
Example choose x=3
-2x3+5<7
-6+5<7
-1<7
Answer:
63
Step-by-step explanation:
let the two numbers be x,y (x>y)
Then x+y = 16 and x-y = 2
We know that (x+y)^2 - (x-y)^2 = 4xy
So 4xy = 16^2 - 2^2 => 4xy = (16+2)(16–2)
So xy = 18×14/4 = 63
Product of the numbers = 63
The area of shape is the amount of space on it.
The cost to carpet the room is $224
From the floor plan (see attachment), we can divide the room into two shapes:
- <em>A 8ft by 6ft rectangle</em>
- <em>A 4ft by 2ft rectangle</em>
<em />
So, the area of the floor plan is:



The unit cost of carpet is <em>$4 per one square foot </em>
So, the cost to carpet the room is:


Hence, the cost to carpet the room is $224
