Can someone please answer. There is a picture. It is only one question. Thank you so much!

We can check each of these using the Pythagorean Theorem, a^2 + b^2 = c^2
Option A: 
.5^2 + 1.2^2 = 1.3^2


.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B
1^2 + 2^2 = 3^2
1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
This option works
Option D:
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
This option works

So, after doing the calculations, we see that option B does not work

Vlad1618 [11]

Answer: -4, -3, -2

Step-by-step explanation:

By inspection, we know x=-2 is a root.

We can thus rewrite the equation as

(x+2)\left(\frac{x^3 + 9x^2 + 26x+24}{x+2} \right)=0\\\\(x+2)(x^2 + 7x+12)=0\\\\(x+2)(x+3)(x+4)=0\\\\x=-4, -3, -2
