Answer:
feet tall
Step-by-step explanation:
Ajax is "5 and 1 fourth feet tall", which can be written as the mixed number .
His sister is "3 eighths foot shorter", so she's 3/8 feet shorter than 5 1/4.
So, this is just a subtraction problem:
To solve this, we want to convert 5 1/4 into an improper fraction, which is: . Now, we want to find a common denominator. In this case, that common denominator is 8, so .
Finally, we subtract 3/8 from 42/8: . So, Ajax's sister is 39/8 feet. Converting this into a mixed number, we have: 39/8 = 4 .
Therefore, Ajax's sister is feet tall.
Hope this helps!

Answer:
2-square root 3, 2+ square root 3
Step-by-step explanation:
If the polynomial has rational and real coefficients, the roots will be "conjugates" of each other. That is, the sum of the root should be a rational number. So, the irrational parts will be opposites, while the rational parts remain the same.
2±√3 . . . can be the roots of p(x) when p(x) has rational real coefficients
