Yes, as the value of x increases so does the value of y hence they are (directly) proportional
(3x+4) (2x-6)
6x-18x+4x-24
6x^{2} -14-24
Answer:

Step-by-step explanation:
If x varies directly as the product of p and m, and inversely with y, the relation can be written ...
x = k(pm)/y . . . . where k is the constant of proportionality
__
This can be solved for k:
k = xy/pm
For the given values, the value of k is ...
k = (2)(4)/((0.5)(2)) = 8
Then the relation between the variables can be written ...
(xy)/(pm) = 8
Answer:
12
Step-by-step explanation:
Using the formula
A=wl
Solving for l
1=a/w=24/2=12
