Answer:
15
Step-by-step explanation:
Move the -5 over by adding 5 to both sides
3x^2+4x+5=0
must use quadratic formula
for an equation in the form
ax^2+bx+c=0

a=3
b=4
c=5

You could use the Pythagorean Theorem to find this. Since the two legs will be the same length:
5² + 5² = c²
25 + 25 = c²
50 = c²
√50 = √c²
5√2 = c
so the hypotenuse length is 5√2
