Answer:

Step-by-step explanation:
Given
c varies directly as w
Required
Write the equation
c varies directly as w.
Mathematically, this is represented as:

Convert to equation.

<em>Where k is the constant of variation</em>
Answer:
Step-by-step explanation:
P≥300
300≤P
P=2(L+W)
300≤2(L+W)
L=3
W=x+5
300≤2(3+x+5)
300≤2(8+x)
divide both sides by 2
150≤8+x
minus 8 both sides
142≤x
x is at least 142
width is at least 147
