We evaluate b^2 - 4ac. If the answer is positive, then there are two real solutions. If it is zero, there is one real solution. If it is negative, there are 2 complex solutions. In this equation, a = 1, b = 5, c = 7. Now we plug in the numbers.

Because this answer is positive, there are two real solutions.
Answer:
Since the least number of digits in the number is 2 decimal places

Answer:
y = 4
Step-by-step explanation:
Since the 2 rectangles have the same area, then
12.5 × 2y = 5 × 20
25y = 100 ( divide both sides by 25 )
y = 4
