Answer:
2 real solutions
Step-by-step explanation:
To determine the nature of the solutions use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real solutions
• If b² - 4ac = 0 the 2 real and equal solutions
• If b² - 4ac < 0 then no real solutions
Given
x² + 9x + 20 = 0 ← in standard form
with a = 1, b = 9, c = 20, then
b² - 4ac
= 9² - (4 × 1 × 20 ) = 81 - 80 = 1
Since b² - 4ac > 0 then there are 2 real solutions
Since the degree measure of the segment 0-19 in Adley is 70*, and the degree measure of the segment 0-19 in Bridford is 60*...........
The proportion is simply 70/60 or 7/6 in simple terms.
