9.22 cm

Step-by-step explanation

To answer this question, you're going to use the pythagorean theorem:

a² + b² = c²  (c is always the hypotenuse, AKA the longest side)

First, let's subsitute our known variables into the equation:

6² + b² = 11²

Next, simplify:

36 + b² = 121

Now isolate the unknown by subtracting 36 from both sides:

b² = 85

Lastly, simplify:

=

b = 9.22 (this is rounded to the nearest hundredth)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

50-38=12
