Once again help please

B.

Step-by-step explanation:

Using Pythagoras theorem

c² = a²+b²

Where c = hypotenuse, a = base and b = perpendicular

So putting the givens

c² = (2√5)² + (6)²

c² = 20+36

c² = 56

Taking square root on both sides, we get

c = √2×2×14

c = 2√14

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
