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
We can factor this using the AC method.
We can split the middle term using the factors 4 and -9
x^2 + 4x - 9x - 36
Factor by grouping.
x(x + 4) - 9(x + 4)
<h3><u>(x - 9)(x + 4) are the factors of this polynomial.</u></h3>
