A triangle has side lengths 1.5 cm, 2 cm, and 3 cm. Is this a right triangle? Explain.

No

Step-by-step explanation:

To figure out whether a triangle is a right triangle using only the side lengths, you can use the Pythagorean theorem:

a^2 + b^2 = c^2

1.5^2 + 2^2 = 3^2

2.25 + 4 = 9

Since this equation isn't true, these numbers cannot be the side lengths of a right triangle.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
