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
Answer:
8
Step-by-step explanation:

Answer:
29 points
Step-by-step explanation:
Jamal+Joey=65
We know Jamal has 36 points so...
36+Joey=65
subtract 36 from both sides
36-36+Joey=65-36
Joey=29
