$ (20b + 80) is the cost to buy a frame for the panting given that measures b meters by 4 meters and charges $10 per meter for a wooden frame. This can be obtained by finding the perimeter of the painting and multiplying with the cost of wood per meter.
<h3>What is the cost of buying a frame for the painting?</h3>
Given that,
length of the painting (l) = b meters
width of the painting (b) = 4 meters
Perimeter of the painting = 2(l+b)
= 2(b+4)
= 2b + 8
Cost of the frame = (2b + 8)× $10 per meter
= $ (20b + 80)
Hence $ (20b + 80) is the cost to buy a frame for the panting given that measures b meters by 4 meters and charges $10 per meter for a wooden frame.

P=Perimeter
L=Length
W=Width
Hints given are P= 76, L=20 so 2L=40
76=40+2w
76-40=2w
36=2w
18=w
Answer:
g(x) x^2 - 5
------ = --------- where x ≠ - 1/4
f(x) 4x+1
Step-by-step explanation:
f(x) = 4x+1
g(x) = x^2 - 5
g(x) x^2 - 5
------ = ---------
f(x) 4x+1
The denominator cannot equal zero
4x+1 ≠ 0
4x≠-1
x≠-1/4
g(x) x^2 - 5
------ = --------- where x ≠ - 1/4
f(x) 4x+1
The answer would be 15:10
So in it's simplest form the answer would be 3:2 because you would divide each side by 5
Hope this helps :)
