Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours
If x< -5 then x+5 < 0
but the absolute value of x+5 > 0
the value of x is 5 feets and p = 2, q = 6 and r = 16.
What is a rectangle?
Rectangles are quadrilaterals having four right angles in the Euclidean plane of geometry. Various definitions include an equiangular quadrilateral,
Area of rectangle is A = a*b
Perimeter = 2(a+b)
given in the question that the perimeter is 16 feet.
p= 2(3+x)
p = 6+2x
p = 2
q = 6
r = 16
2x = 10
x =5 feet.
Hence, the value of x is 5 feets.

Answer:
Step-by-step explanation:
i think that it is C but not 100% sorry
Divide both sides by 12 to get x by itself
so it looks like:

that's it
