Answer:
460 ft^2 of carpet will be replaced
Step-by-step explanation:
You need to find the area of the room and then take away the area of the six bookcases
<u>Area of the room</u>
20*20=400ft^2
35-20=15ft
(15*20)/2=150ft^2
400+150=550ft^2 total room area
<u>Area of bookcases</u>
2.5*6*6=90ft^2 total bookcase area
<u>room area - bookcase area = carpet area</u>
550-90=460ft^2
3x+3-x+(-7)>6
combine like terms on left side
2x-4>6
add 4 to both sides 2x>10
x=10/2 = 5
x>5
Answer:
D. 130 feet
Step-by-step explanation:
<u>Data</u>
- The area of a circular garden is 4,225 π square feet
The area of a circle is computed as follows:
Area of a circle = π*D²/4
where D refers to the diameter
Replacing with data:
4,225 π = π*D²/4
4,225 π/π *4 = D²
√16900 = D
130 ft = D
Yes
if you had less than 2, the lines wouldn't cross each other and wouldn't form a triangle
