hope this helps :D
Answer:
<h3>D</h3>
Step-by-step explanation:

W = L - 15
WL = 76
(L-15)L = 76
L^2 - 15L - 76 = 0
(L-19)(L+4) = 0
L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
A- the grams of copper is total which is 128 grams.*** b- is the total amount of percent of copper which is 71.76%+9.37
The amount of fiber needed in a day is 7.98 grams
<h3>Proportions</h3>
Proportions are parts, in comparative relation to a whole.
In other words, proportions are fractions of a larger dataset
The given parameters from the question are given as:
- Proportion of the daily value of fiber needed = 57%
- Daily serving = 14 grams.
<h3>
Amount of
fiber</h3>
The amount of fiber needed in a day is the product of the proportion and the size of the daily serving.
So, we have:


Hence, the amount of fiber needed in a day is 7.98 grams
