Solve by factoring
x = -12
x = 3
The expression for the number of segments drawn out of the n number of points in the circle is,
n² / 2 - n / 2
Substituting directly to the expression the number of points, n, which is equal to 8,
8² / 2 - 8 / 2 = 28
Thus, there are 28 segments that can be drawn from the points.
Answer:

Step-by-step explanation:



For this problem, let's assign a variable for the total amount of proteins needed daily/ Let that parameter be x. Now, the 48 grams is part of the total. The other portion is the one expressed in percentage. That accounts for 4% of x. Therefore, the equation would be:
x = 48 + 0.04x
Solving for x
x = 50
Thus, you will need 50 grams of protein daily.
