Triangle area is 1/2 bh
So 11.9 is about 12, 7.1 is about 7.
7x12 = about 84 sq, cm
Answer:
x=4
Step-by-step explanation:
2x-3=5

divide both sides by 2
x=4
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

The width is x+2.
The length is x+4.
The area is the product of width and length.
.. Area = (x +2)(x +4)
.. = x^2 +6x +8
