Answer:
x=2
Step-by-step explanation:
Percentage of red haired students = 2%
Total number of students = 700
Therefore,
Number of students with red hair = Total number*Percentage of the red haired students = 700*2/100 = 14
Then, 14 students have red hair.
4x²=16
x²=16/4
x²=4
√(x²)=+/-√4
x(1) =2, x(2)=-2
