The lengths of three sides of a quadrilateral are shown below:

pentagon [3]

In part A, we need to solve for the total length of sides 1, 2 and 3.
Since all three sides measurements are given, we have the solution below:
Sides123 = Side 1 + Side 2 + Side 3
Sides123 = (3y² + 2y - 6) + (4y² + 3y -7) + (5y² + 4y -8)
Sides123 = 12y² + 9y - 21
This is the total length of sides 1,2 and 3 "12y² + 9y - 21"

In part B, we need to solve for the length of the fourth side and the solution is shown below:
Side 4 = Perimeter / Sides123
Side 4 = (4y³ + 18y² + 16y -26) / 12y² + 9y -21

Out of a class of 150 students, two-fifths opted for German classes and one-third opted for Italian classes. The remaining opted

Yuliya22 [10]

Fraction of students that opted for French = $\frac{4}{15}$

The total number of students = 150

Fraction of students that opted for German = $\frac{2}{5}$

Fraction of students that opted for Italian = $\frac{1}{3}$

Fraction of students that opted for French = 1 - Fraction of students that opted for German - Fraction of students that opted for Italian

Fraction of students that opted for French = $1-\frac{2}{5} - \frac{1}{3}$
