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!

So, I'd say you are correct.
Answer:
We simplify the equation to the form, which is simple to understand
5x+15=4x-12
We move all terms containing x to the left and all other terms to the right.
+5x-4x=-12-15
We simplify left and right side of the equation.
+1x=-27
then divide both sides of the equation by 1 to get x.
x=-27
