Answer:
-1
Step-by-step explanation:
|x-4|=x-4 when x-4 is positive or zero.
|x-4|=-(x-4) when x-4 is negative or zero.
x-4 is positive or zero means:
x-4>=0
Add 4 on both sides gives:
x>=4
x-4 is negative or zero means:
x-4<=0
Add 4 on both sides gives:
x<=4
Now we are approaching values of 4 from the left which means these values are less than 4 which makes x-4 negative.
So we are using:
|x-4|=-(x-4) when x-4 is negative or zero.
As x approaches 4 from left we have:
|x-4|/(x-4)=-(x-4)/(x-4)=-1.
Answer:
cylinder volume= 1005.30965cm²
rectangular prism volume= 384cm²
total volume: 1005.30965+384= 1389.31cm²
36 -81.9 - 45.9 I keep getting -45.9
Answer:
Length of the garden = 10 ft
Step-by-step explanation:
Perimeter of a garden = 2(length + width)
Perimeter of the garden = 32 ft
Width of the garden = 6 ft
Length of the garden = x ft
Perimeter of a garden = 2(length + width)
32 = 2 ( x + 6 )
Open parenthesis
32 = 2x + 12
Subtract 12 from both sides
32 - 12 = 2x + 12 - 12
20 = 2x
Divide both sides by 2
20 / 2 = 2x / 2
10 = x
x = 10 ft
Therefore, length of the garden = x = 10 ft
50:40=x:35
5/4=x/35
times both sides by (4*35)
5*35=4x
175=4x
divide both sides by 4
43.75=x
costs $43.75
