Answer:
b = √2
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
<em>a</em> = Leg₁
<em>b</em> = Leg₂
<em>c</em> = Hypotenuse
Step 1: Plug in variables
3² + b² = (√11)²
Step 2: Solve
9 + b² = 11
b² = 2
b = √2
And we have our answer!
Answer:
The smallest amount is
Step-by-step explanation:

y= 15x
ANSWER: y= 15x (bottom choice)
Hope this helps! :)
