What is the hypotenuse if the base is 2 and the length is 2

hypotenuse = √8 ≈ 2.83

Step-by-step explanation:

The hypotenuse of a right triangle can be found using the Pythagorean Theorem:  a² + b² = c², where 'a' and 'b' are the legs, or base and length, of a right triangle and 'c' is the hypotenuse.  

Substituting a = 2 and b=2, you can solve for c:

2² + 2² = c²  or 4 + 4 = c²  

8 = c², take the square root of both sides:  √8 = √c²

√8 = c or approximately 2.83

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
