Answer:
<h3>               
A =  ²⁵/₄x² + ⁷⁵/₂x + 50</h3>
Step-by-step explanation:
L = ⁵/₂x + 10
W = ⁵/₂x + 5
A = L•W
A = (⁵/₂x + 10)(⁵/₂x + 5) 
A = ⁵/₂x•⁵/₂x + ⁵/₂x•5 + 10•⁵/₂x + 10•5 
A = ²⁵/₄x² + ²⁵/₂x + ⁵⁰/₂x + 50
A =  ²⁵/₄x² + ⁷⁵/₂x + 50
Or if yoy mean: 
L = 5/(2x) + 10
W = 5/(2x) + 5
A = [5/(2x) + 10][5/(2x) + 5] = 25/(4x²) + 75/(2x) + 50

Answer:
The least mood value. 
Step-by-step explanation:
If Julio has rated their mood on a scale from 0 to 10, with 10 being the happiest. The least value is 5.
If the fitted line has a y-intercept of 5, the best interpretation of this y-intercept is that the least mood value among the his fellow students is 5.
Intercept actually means beginning, starting point, flat rate e.t.c
