Answer:
it's b
Step-by-step explanation:
it's b because the lines outside of the equation mean the absolute value of the equation
$ (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.

575 / 14
Use easy multiples of 14 that do not exceed 575. Use 10.
(1) 14*10 = 140 575 -140 = 435
(2) 14*10 = 140 435 - 140 = 295
(3) 14*10 = 140 295 -140 = 155
(4) 14*10 = 140 155 - 140 = 15
Now you cannot use another 10*14. Then just divide 15 by 14 which gives 1 and have remainder 1
(5) 15/14 = 1
15 - 14 = 1 = Remainder
Then, the sum of the partial quotients is 10+10+10+10+1 = 41; and you have remainder 1, therefore 575 = 41*14 + 1
And the result of the division is 575/14 = 41 plus remainder 1
