Add 18 to both sides
2y = 3x + 18
Answer:

Step-by-step explanation:
1. To calculate the area of the grass you must substract the area of the square and the area of the circle.
2. The area of the square is:

Where
is one side of the square.
3. You have that:

4. Therefore:

5. The area of the circle is:

6. The are of the grass is:

Answer: Option 'a' is correct.
Step-by-step explanation:
As we know about the discriminant value i.e.
if we have given a quadratic equation :

then,
discriminant value will be

There are 3 properties regarding discriminant value as follows:

So, here we need a zero real number solutions i.e. there does not exists any real number.
So,

Hence, Option'a' is correct.
Answer:
True.
Step-by-step explanation:
The artists is using simple math. When cutting squares from the corners he uses the same measure for each side of the figuer (because is a square) and the remaining sides thatare folded havethe same measures as the squares.
Cutting each side with the correct percent of the total surface in order to go from 20 in to 15 in.
Use distributive property for each side of the equation
1.) 10(x+2)>-2(6-9x)
2. 10x + 20> -12+18x
Then whatever you do to one side of the equation, you do to the other. So we’re trying to get x alone on one side.
Subtract 10x from each side
3.)20> -12 + 8x
Add 12 to each side
4.) 32>8x
Divide each side by 8 to get x alone
5.) 4 > x
