Answer:
D
Step-by-step explanation:
Square root of 4 is 2
square root of 9 is 3
so square root of 5 should be somewhere between 2 and 3 (closer to 2)
Step-by-step explanation:
y=-27

The answer for 8 is C
The answer for 9 is A
The square is shown with a side length of 8 inches.
The area of a square is s^2, which can also be written as s x s, where a is the length of the side.
Area of the square would be 8 x 8 = 64 square inches.
The area of a circle is pi x r^2, where r is the radius. R is given as 3 inches.
The area of the circle is 3.14 x 3^2 = 28.26 square inches.
The shaded area is the square minus the circle.
The shaded area = 64 - 28.26 = 25.74 square inches.
The answer is 25.74 square inches.
Answer:
54 feet
Step-by-step explanation:
The perimeter of the room is the sum of wall lengths:
2·(15 feet) + 2·(12 feet) = 30 feet + 24 feet = 54 feet
The border should be cut to 54 feet.

<em>Comment on the question</em>
This seems to be a math problem designed to get you to figure the perimeter of the room. If you were actually installing wallpaper, you might want to cut the border in four (4) pieces, each slightly longer than the corresponding wall. That way any lack of squareness in the corners could be managed more easily, and the possibility of a gap at the seam could be eliminated.
