Answer:
yes ! it's a rational number.
Step-by-step explanation:
<em>The square root of 16 is 4, which is an integer, and therefore rational.</em>

Given

We have to set the restraint

because a square root is non-negative, and thus it can't equal a negative number. With this in mind, we can square both sides:

The solutions to this equation are 7 and -2. Recalling that we can only accept solutions greater than or equal to -1, 7 is a feasible solution, while -2 is extraneous.
Similarly, we have

So, we have to impose

Squaring both sides, we have

The solutions to this equation are 5 and 10. Since we only accept solutions greater than or equal to 7, 10 is a feasible solution, while 5 is extraneous.
Answer:
5b=2f
Step-by-step explanation:
Priya uses
cups of floor to make 3 loaves of banana bread.
Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.
To find the relation between b and f, the steps are as follows :

It means,

So, the relationship between b and f is "5b=2f".
