Step-by-step explanation:
Answer:
the number of blonde hair is 10
The computation of the number of blonde hair is shown below;
Given that
Ratio of blonde to brunetees is 2:3
And, there is total of 25 students
So, the number of blonde hair is
= 25 × 2 ÷ (2 + 3)
= 25 × 2 ÷ 5
= 10
Hence, the number of blonde hair is 10
Using FOIL we get:
xy + 8x - y - 8
X = 8/3 + X^2/3
X = -4 ± i
