210, 420, 630, 840
multiples of 2*3*5*7
Answer:
The answer is 
Step-by-step explanation:
Volume of the rectangular prism = Length * Width * Height
Length (l) = 
Width (w) = 
Height (h) = 
By substituting these values to the equation above,
Volume of the rectangular prism = 
=
=
=
Therefore,
The answer is 
Answer:
x=1
Step-by-step explanation:
Answer:
see in the picture, the perimeter of this rectangle is
2( x + 3x) = 8x but the perimeter is 65.6
=> 8x = 65.6
<=> x = 65.6/8
=> x = 8.2
The best way to answer this would be making a graph
For 1 sign it costs 54.50 and he makes 15
For 2 signs it costs 59 and he makes 30
For 3 signs it costs 63.50 and he makes 45
For 4 signs it costs 68 and he makes 60
For 5 signs it costs 72.50 and he makes 75
This means that after 5 signs Larry will be making profit
