Perimeter = 2L + 2w
in this case, L = 3w - 2 and perimeter = 28.
so, 28 = 2L + 2w.  or 14 = L + w.  or substitute for L: (3w - 2) +w =14 
or 4w - 2 = 14.  4w = 12. 12/4 = 3 = w.
The width = 3 inches; and the length = (3x3 -2) 7 inches.

Answer:

g(x) = 5x + 2.

r(x) = x

b(x) = 1/2 x³

k(x) = - 3 x + 1

Step-by-step explanation:

The function notation ⇒ it is the form to write the function, It is meant to be a precise way of giving information about the function, like f(x) , v(x) and so on.

Given the following:

g(x) = 5x + 2.

y = 1 x

h = x²

r(x) = x

f/x = x⁵ - 3

b(x) = 1/2 x³

p/x = -7x

k(x) = - 3 x + 1

y = mx + b

fx = -x³ + 4

So, in the given options the following are in function notations:

g(x) = 5x + 2.

r(x) = x

b(x) = 1/2 x³

k(x) = - 3 x + 1
