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:
sln
3b-2a=7
3b-7=2a(divide by 2 both sides)
a=3b-7/2

Answer:
the store offered the better deal
Step-by-step explanation:
the store was only 20 dollars and online e was 42 so the store had the better deal
If <em>f(x)</em> is a density function, then its integral over the entire real line should be 1:

so yes, <em>f(x)</em> is indeed a density function.
