You can predict that it's odd because the end of the 2 numbers is 1 and 1 x 1 is 1 and one is an odd number. (answer is odd)
The answer is 6. plug it in for yourself and you will see
Answer:
$1200
Step-by-step explanation:
Let the roof be square shaped
Area of the roof = L²
L is the side length of the roof
Given
L = 40ft
Area of the roof = 40²
Area of the roof = 1600ft²
If plants used for a green roof cost $0.75 per square foot, this means
1 ft² = $0.75
Let the cost needed to cover both sides of the roof be y, hence;
1600ft² = y
Divide both expressions
1/1600 = 0.75/y
y × 1 = 0.75×1600.
y = 0.75×1600
y = 1200
Hence it will cost $1200 to cover both sides of the roof
Answer:
Option D that is y=-2(x+1) is the correct choice.
Explanation:
Given equation:
We have to find another equation which has only one solution.
Standard form of equation:
Condition for one solution.
We have to arrange other equation in the form of 
Mark all the options as a,b,c and d.
Now from the above options we can see that option 
are not providing the desired result.
So
can be obtained from the last option.
As
Option D that is 
is the equation from where we can obtained only one solution.
