√7 is not a perfect square , so it's irrational
Answer is B. irrational numbers
P.S .
Keep in mind that any of non perfect square is irrational
Answer:
Call the numbers a, b, c, d. What does it say if their mean is 15? That would be that added together then divided by 4 you get 15. So the number before you divided by 4, which is the sum, was 60. If you know some algebra, the equation (a+b+c+d)/4=15 gives the sum of 60 when you multiply both sides
Answer:
Rewrite the equation as 4L+4W=P.
4L+4W=P
Subtract 4L from both sides of the equation.
4W=P−4L Divide each term by 4 and simplify.
W=P/4−L
Step-by-step explanation:
For this case we have the following polynomial:
Rewriting the polynomial we have:
From here, we can solve the polynomial using the quadratic equation
We have then:
Therefore, the solutions are:
