Solve for c :
x⁴ + cx² + 100 = 0
cx² = -(x⁴ + 100)
c = - (x⁴ + 100)/x²
If x = 0, the right side is undefined and c would have no solution.
Answer:
27, you need to simplify both sides of the equation to get x on one side.

Answer:
18 ducks
Step-by-step explanation:
add the parts of the ratio 7 + 6 = 13
divide the total by 13 to find one part of the ratio
= 3 ← 1 part of the ratio
7 parts = 7 × 3 = 21 ← number of swans
6 parts = 6 × 3 = 18 ← number of ducks
